- The bug when importing USGS DRG maps has been found. It occurred when a map was imported
and the "Map File Path" in configuration was empty or the "Map File
Path" when importing a full CD of maps was not entered.
- Probable bug when importing USGS DRG maps which was introduced in the last version,
could not directly find the problem but I made some fixes to a new section of code which
may have been the cause.
- Use Grid in the Transverse Mercator Projection now allows the Easting and Nothing to
have a minus sign.
- Navigation options were disabled when right clicking on Map Feature without a waypoint,
but they were not turned back on, now fixed.
- Proximity waypoints would sometimes plot in the wrong place on the map when in fact they
should not be on the map at all, this has been fixed.
- 16 color TIF files can now be used.
- Can now import the DRG maps from Wyoming web site - see help section "Importing
USGS DRG Maps" for details.
- Although not recommended you can now import DRG files which only have the .tif and the
- You can now turn on or off the checking of the Check Sum for NMEA
- There has been other subtle changes to the comms setup and the reading of NMEA
- I have changed the colour for the "tooltips", the tips that appear when you
put the mouse on a button or waypoint etc. These now show in the same color you have set
for windows tooltips which you set in the appearance tab in the display settings.
Not actually released
Version 3.64b has internal problems with the code which were created when a compiler
directive was changed from previous versions. This can result in unexpected
"crashing" of the software which usually results in windows being corrupted and
a reboot being required. If you have a 3.64b version you should delete it. This does not
happen on all systems, my desktop does not show the problem but it causes my laptop to
crash consistently. All the other changes made in version 3.64b to fix bugs etc are still
valid and are in 3.64c.
For the technical minded the compiler directive changed was "Code Optimization was
turned on", this is not supposed to have any effect on the operation of the code. As
the compiler help file says "All optimizations performed are guaranteed not to alter
the meaning of a program. In other words, no "unsafe" optimizations are
performed that require special awareness by the programmer." , ah well.
- Fixed problem with Potsdam datum, referencing wrong ellipsoid.
- Some minor fixes, mainly fine tuning, especially of the Moving Map operation.
- Waypoint Name and Map Comment background colors now have a transparent option.
- Map Comments now have the ability to change font size and select "bold" style.
- There is now the ability to link the Map User Grid (Transverse Mercator projection),
which is setup when calibrating, to the User Grid which you setup in the configuration for
onscreen coordinate display. There is a new option on the "Map" tab in
configuration to specify "Use map User Grid". If this is true and the map being
loaded has a user grid set, the "map user grid" is automatically copied to the
"Alternate Grid" for coordinate display.
- Finally found problem and fixed it (I hope) with the Mag Variation calculation when
using the NMEA simulator, traced problem to international settings, when the decimal
separator being used was a comma it resulted in an extra comma being inserted into the
- The Moving could give a terminal error when first started when it needed to change maps,
the errors were various including "Division by Zero", but the cause was the
same. These type of dynamic bugs can be difficult to find but I did find something and
- Closing OziExplorer while receiving NMEA data from the GPS (Moving Map) would sometimes
result in an "Access Violation" error, caused by closing files etc when the last
NMEA sentence was still being processed, now fixed.
- The track file names are now remembered correctly when resaving the files from the
- and the usual minor housekeeping type changes.
- Version 3.64a added a larger "blank map", this caused the load times of the
"normal" maps to be increased because before loading any map a "blank
map" was always created to put the system into a known state. In this version the new
"blank map" has been refined and may be quicker to create, however, the
"blank map" is no longer created when loading a "normal" map. Load
times should actually be quicker now than any previous version. BUT, this has meant
recoding of the map load procedures which can of course add in new bugs and problems, but
testing has not shown any.
- There have been a few changes to stop data (waypoints, map data etc) from being lost
when changes have been made. You will now be prompted before any changed data is
- Added 2 new symbol pointers for Moving Map, a cross and a new simple boat.
- Removed bug in the "Find Map" routine. If you were in any zoom level other
than 100% the calculations used to find the available maps were incorrect.
- Fixed bug in Position Edit in the properties window of waypoints etc. only when editing
in UTM coordinates. This was a recent bug only in 3.63f and 3.64.
- Some other minor bugs.
- Many changes for Windows "Large Font" support, OziExplorer should look much
neater now. But optimization has been done for small fonts so there will still be some
things slightly out of place.
- The Austrian datum (or 1 of them) has been added.
- The Geocentric Datum of Australia (GDA94) has been added.
- OziExplorer will now also use the GLL sentence for NMEA if the RMC or GGA sentences are
- You can now double click on any map object (Waypoint, Event, Map Feature or Map Comment)
to open the properties window.
- The "Blank" map has been increased in size by a factor of 2.5, this means the
blank map is this much bigger and effectively increases the zoom level available by 2.5
over previous versions. The max zoom available is still 7.5 (750%) but the map is now 2.5
- The Grid has been modified and a selection of Grid intervals has been added for the blank
map, these are located on the map menu.
- The routes being navigated had a bug where the bearing was being displayed as Magnetic
when in fact it was a True bearing.
- Found bug in Magnetic Variation calculation.
- quite a few minor fixes.
- The Cursor Zoom Window is now selectable for display at startup.
- When calculating distances there is now a choice of a using a spherical method or
ellipsoid method. OziExplorer was using the spherical method only, the difference is about
1%. I assume the ellipsoid method should be the more accurate. See the configuration help
for a little more info.
- Found the bug in Magnetic Variation calculation (a bit of development code left behind)
and did a bit more fine tuning of the handling of Magnetic Variation, see the help topic
for a description of how OziExplorer deals with this.
- Some fine tuning to the Magellan drivers.
- When using "Moving Map" there is now an option to project (draw) a line from
your present position along your current course.
- When using "Moving Map" your present position plots on the "MapView"
- Version 3.63e Map Features had a bug where they would disappear after changing the
- Magnetic Bearing had a bug, the calculation was not correct in certain circumstances.
- The bearings in the Moving Map and Navigation Controls now only display whole numbers
(not 1 decimal place as before), if this causes problems let me know.
- For Map Features if the "picture" file name had spaces within the name it
would not load and be displayed, fixed.
- The Track description in the Track Control could not always be accessed and changes were
not always recognised.
- The Track default color and width were not correctly used after being altered in the
Track Control, this showed when adding track points.
- The editing of waypoints in UTM using the waypoint editor had an error if the
coordinates were in the Southern Hemisphere.
- The MagVar in the NMEA simulator had "W" (west) hardcoded into it so it always
assumed the MagVar was to the west.
- Full support has been added for the Garmin GPS III. This includes the modified
protocols, the correct selectable symbols on screen and of course the ability to upload
and download the waypoint symbols and display formats to the GPS.
- You can now specify the waypoint name for a Map Feature, this is on its property window.
Note that if you do not want these Map Feature waypoints to be downloaded when using the
"Merge Waypoints from GPS" option the waypoint name must start with
"MF" (hopefully only temporary until I code a new fix).
- The ability to edit the position of a Map Feature has been added to its properties
- Quicker clearing of Routes - this took a considerable amount of time on slower PC's, 10
to 15 secs, it will be much faster now.
- There are now options on the Map Menu to allow the adding of waypoints, events etc.
- There are now options on the Map Menu to show the Zoom window and MapView.
- The Zoom when the PgUp or PgDn down was hit for the first time has now really been
fixed, (yeah sure).
- There was a comm problem when using NT4 and attempting to communicate with the GPS after
using a modem on the same serial port, it would not work. Traced the problem and hopefully
- As well as the "Man Overboard" waypoint there is now a "Position
Marker". These can be set at the current GPS position while using "Moving
Map". These are just special types of Waypoints with their own symbols.
- In version 3.63c I was experimenting with setting the BMP images to 8 bit color in the
code, this was causing color changes on some systems, this has now been removed. Please
not however that on some systems OziExplorer does not like to use 16 color BMP images.
- When printing BMP or JPG files I was reloading the whole image again, this was to
overcome a technical problem which has now been rectified (possibly). The images will not
be reloaded again, this should give 2 advantages for large files, the images will start
printing much quicker and there is much less chance of running out of memory resources.
Let me know if this still causes problems.
- Also when printing TIF files I needed to create a tempory BITMAP to hold the portion of
the image for printing, this is a tradeoff between memory requirements and printing speed.
The size of the BITMAP required was about 4Mbytes, I have now reduced the size to about
2Mbytes, this should allow systems with tight memory resources to have a better chance of
printing. Let me know if you still have problems.
- Please note in calibration mode you now need to also hold down the shift key when using
the arrow keys to move the calibration points.
- The zoom was not correct when the PgUp or PgDn key was hit the first time, fixed.
- Waypoints added with the new waypoint editor were not able to be uploaded to
Lowrance/Eagles, a parameter was not set correctly, now fixed.
- Scrolling the map using the cursor keys when in calibrate mode were still enabled, this
cannot be allowed and has now been turned off.
- When the "Last Map" was loaded and scrolled to the "Last Position"
the "MapView" window did not update correctly, now fixed.
- The "Distance Display" window could not be activated correctly from the Menu
etc, now fixed.
- When drag map was enabled (hand cursor) and the map was clicked to exit from a menu the
map was not refreshed correctly, fixed.
- In order to print maps accurately at a specific scale it required a more accurate method
to calculate the scale. This resulted in a situation where 2 maps of similar scale would
be loaded alternately (continuously) when using moving map. This was caused by the new
calculated scale not agreeing with the old scale stored in the map file. To fix this I
have placed a tolerance of 2% on changing to a better scale map. This means if a map is
not at least 2% better in scale factor (more detail) than the current map it will not be
loaded. This avoids those calculation type problems with floating point numbers as well as
my coding changes.
- Polyconic (American) and Albers Equal Area projections have been added.
- The ability to add a "Man Overboard" waypoint at your current position (when
using Moving Map) has been added. This is on the Moving Map menu and the right click map
menu and the "Alt+O" key combination. The waypoints now have a new Display
format called, what else, "Man Overboard".
- Bug in reading xml metadata files from Penn. State University.
- There is a bug in Navigation to waypoint feature, found a problem and fixed it, but not
sure if it was the correct problem?
- Many minor fixes.
- A lot of fine tuning to get ready for non-beta release in the near future.
- Completely new map printing functions, completely rewritten, now with print to scale -
any scale you like to select or enter. These changes have hopefully removed most of the
GPF problems of the old method.
- I have made extensive changes to the Magellan drivers and have found some more info on
how to interface with these units, actually it was no secret I just had to work out how to
do it properly. I have changed the name of the 2nd Magellan driver to Magellans (No
Handshaking). I think that ALL Magellans should now work with either driver, the
preferred driver being the Magellans one, this provides for upload/download using
the full handshaking protocol which should be more reliable.
- The zoom levels can be adjusted using the PgUp and PgDn keys. The map screen must have
- The map can be scrolled using the arrow keys. In calibration mode the calibration points
can be moved by holding down the shift key and using the arrow keys.
- There is a goto waypoint button on the waypoint list window. The waypoint must be
located on the current map.
- You can now specify in configuration that when the last map is loaded the last map zoom
level is selected and the map scrolls to the last map position being used.
- The last map datum being used for calibration is remembered.
- When loading maps etc the last directory accessed is now remembered.
- The event list now has the ability to display positions in the various grid formats.
- When calibrating using the user grid in a Transverse Mercator projection you now enter
the calibration points in the user grid coordinates.
- many improvements to allow OziExplorer to run direct from a CDROM.
- The Esc key will now exit many of the windows.
- Many Shortcut keys have been set up and can be seen on the menus.
- The amount of windows resources being used has been reduced.
- The maximum number of routes has been increased to 100 to handle the new Lowrance Global
- Waypoint editor has been done and is available from the Waypoint List window.
- The icons for the Magellans have been slightly improved.
- It is now possible to input Lat/Lon position formats in DMS as well, this is only a
limited solution as they cannot be shown in DMS. When entering into the Minutes field if
you enter as say 43 53.123 this is read as 43 minutes 53.123 seconds.
- There is a new way of displaying Lines and Distance between 2 points on the map.
- You can now select the ability to show a line from the mouse cursor to the current map
- The NMEA simulator always assumed a Magnetic Variation of 3 degrees west. This has now
been changed to use the Mag var entered with the map calibration. An extra feature has
been added to automatically calculate the Mag Variation if it has not been entered
with the map calibration. It is automatically calculated whenever a Mag variation is
required to obtain a Magnetic bearing. No guarntee on how accurate it is though.
- New "Conditions of Use" window pops up when you start OziExplorer. After you
read it simply click the "Do not show this message again" box to remove
- I have added 38400,57600,115200 Baud rates but have not yet tested them thoroughly, they
seem to work ok.
- When downloading tracks from a Magellan the Altitude is now captured, also when
collecting track details using Moving Map the Altitude is collected if the GGA NMEA
sentence is available. These altitudes are not used other than being saved in the track
data file (.plt file).
- The Altitude for waypoints is now captured from Magellans and displayed in the waypoint
hint if available.
- There is a new window available on the Moving Map menu to display the GPS fix
information. Naturally only available when using NMEA communication.
- If you right click on the map a popup menu will appear which has various options
available. To acommodate this the way of adding waypoints, events etc has been changed,
there are now new buttons on the Toolbar for these functions.
- I tried to add the Robinson projection but there seems to be a bug in the
algorithm so I have had to remove it until it is sorted out.
- The position indicator for moving map was not plotting in the correct position when the
map was zoomed. Now fixed.
The implementation of the Magellan upload/download support should now work reasonably
well. This version includes fine tuning of the protocol to remove some timing problems
which caused problems when uploading routes etc. This version also includes the
implementation of a variation in the way Magellan has used their protocol, this variation
is called Magellans (other) in the GPS configuration. New waypoint symbols have
been added for Magellans, these were taken from the Magellan Color Trak and designed from
descriptions so may not look quite correct, I do not know how these relate to other
- More fixes to NMEA bearing calculations.
- Fixed bug where waypoints not on the map were mysteriously appearing in places they
- More fine tuning to Magellan support to correct some uploading problems.
- various other minor fixes.
- The Find Map buttons (4 arrows) on the button bar and options on the waypoint list etc
can still be regarded as experimental, I want to change this to only 1 button on the
button bar with a graphical display of the available maps but have not yet had the time.
- There is a new experimental option on the Moving Map menu called Show Regional
Map Window. My wife (and navigator) told me that "moving map" is good but
she would like to be able to see where we are located relative to the next town or
landmark. I have coded the ability to load a map (any map) into a small window (called
Regional Map Window) , this map is linked to the main map and scrolls as the main map
scrolls, your position from the GPS is also displayed on this regional map. It is intended
that a map of the region you are traversing be loaded into this window so you can see a
reasonably large area, this map should be say 1:1,000,000 up to 1:4,000,000 scale. There
are limitations to the small map - it will not automatically load the next map if you
leave the small map, if you run out of map you did not load a map of sufficient extent in
the first place.
- Moving Map and Navigation have been split to separate menus, and the controls split into
- When scanning for (locating) maps for "Moving Map" or "Find Map"
OziExplorer will now look through the default or configured map directory as well as ALL
subdirectories under that directory.
- Support has been provided for older Lowrance and Eagles (AccuNav Sport etc) by reading
and writing data files for the Lowrance WS1 software. This has been implemented for
Waypoints and Events only at this stage. If your GPS will work with the WS1 software you
can now get this data to and from OziExplorer.
- OziExplorer can now read and write track data from the Lowrance GDM software, using the
clipboard, so it is now possible to upload/download tracks to and from GPS receivers such
as the Global Map 12 by using the GDM software to communicate with the GPS.
- The font size used for for printing of the waypoint list has been increased.
- There is now a Navigate To ... option on the Waypoint popup menu (right click
- There is now also a Find Map option on the Waypoint popup menu.
- There is now the ability to hide all waypoints or all events on the Map Menu and unHide
- The printing of Routes has been done (1st draft).
- There is now the ability to specify the directory USGS DRG maps are imported into.
- For Garmins when uploading or downloading after using NMEA output OziExplorer will now
automatically turn off NMEA input when you select an upload/download option.
- Route colors can now be selected by the user.
- The display of individual routes can now be turned off or on.
The Magellan support provided in version 3.61 and in this version 3.62 is only for one
implementation of the Magellan protocol, while the protocols are similar, different model
Magellans implement them in slightly different ways. The other protocol implementation
(that I know off) is being coded ASAP. The current support has been tested and works with
an older 3000XL and a new 2000XL, it is known not to work with at least one 4000XL.
- USGS DRG maps not importing correctly if the East Bounding longitude was against the
zone boundary - fixed.
- Lowrance/Eagles not working correctly with NMEA or upload/download if ALL nmea sentences
are turned on and 4800 Baud rate set - a timeout problem - fixed. However do not use 4800
Baud if there is a faster Baud rate available - performance will suffer.
- Mercator Projection maps had a small error in the projection calculations causing the
waypoints to not be positioned in the correct spot - fixed.
- Fixed bug where waypoints not on the map were mysteriously appearing in places they
should not depending on zoom level.
- MapView will now stay off when it is turned off.
- For Magellan support - if you changed the Baud rate configuration in OziExplorer they
did not take affect until you restarted the software (a bug) - now fixed, no need to
restart OziExplorer now.
- Uploading Routes for Magellans would not work unless the route names were 01,02,03,04,05
- now fixed.
- There was a problem with the calibration window being too narrow when using "large
fonts" in windows - now fixed.
- Problem with navigation - Course to Steer (CTS) was not displayed correctly if the true
bearing is not known, the Magnetic variation is now taken from the map calibration (if
entered) and used to calculate the true bearing (or magnetic bearing if true bearing is
known). There is no guarntee the problem has been finally fixed but I am trying to sort it
- 6 point calibration now will be done using the linear Affine method instead of the 2nd
order polynomial, 7,8,9 points will be done using the 2nd order polynomial.
- This addition is very nice (for registered users) - There is a set of arrow buttons on
the toolbar (and menus) which allows you to select maps from a list of available maps. I
am also working on a feature (not available yet) to display the maps diagramatically as
simple rectangles in their relative positions. The current implementation will show a list
of maps which :
- are available for your position (center of screen) on the currently opened map
- are available North or South or East or West of the currently opened map
- In the Waypoint List dialog there is a new button to enable you to find maps which will
display a particular waypoint.
- A special addition for users of USGS DRG Maps from Pennsylvania State University, the
import DRG option will now use the xml file which you can download with these maps. There
is a special section in the Importing USGS DRG Maps help for importing these maps.
Version 3.60 has caused problems with datums when loading USGS DRG maps. It appears
that there are some NAD27 and NAD83 maps have the same entries in the fgd file even though
they have different datums. I have decided to now load these maps as NAD27 as these seem
to be the most common. The code has been changed accordingly. This now will mean that some
NAD83 datum maps will now have the wrong datum when imported.
IMPORTANT - If the last version you were using was one of
the 3.51 versions you must resave or re-import your map files so the new moving map
information for automatic map changing is stored in the map file. Map files
saved with 3.60a will be OK.
Waypoint editor still not done.
Printing problem with large maps still not fixed.
- When using the Latitude/Longitude Map Projection any coordinates entered in UTM format
when calibrating the map were totally ignored.
- For Moving Map there was a minor bug when automatically loading the next map, the most
detailed map may not always have been selected.
- Fixed various bugs for adding, deleting track points.
- Fixed various problems with NMEA sentences + extras see below.
- Fixed error when closing program when in calibrate mode.
- Fixed bug when importing USGS DRG maps, if there were maps at different scales on the
same CD the map file for each of the scales would overwrite the previous one. The map file
name now has the scale as part of the name, this should now not overwrite and also gives
additional info in the name.
- When importing USGS DRG maps the dialog when done would say Error - there was no error
just an incorrect name used for the dialog.
- Basic support has been added for Magellan GPS receivers. The extra Magellan stuff will
be added gradually. Note - could not get Magellan to download at 19200 Baud (4800, 9600
OK), 19200 works with my Lowrance ??? - and as far as I know it is not possible to upload
the track to a Magellan. The upload/download was tested using a 3000XL..
- The 4,5,6 point calibration method was not working well, the geometry of the points was
too critical. I have changed the software so that 3,4,5 points use a linear affine method
and 6,7,8,9 points use a 2nd order polynomial.
- Support for JPG images has been added. Note that while you get good compression with
JPG's this means that they take longer to load, far too long for large images. I also
convert them to 256 colors during the loading process to reduce the amount of memory
required for large images, you should not notice much difference in the colors. The
preferred format for large images if still TIFF with packbits compression.
- For moving map, OziExplorer will now check at a configurable interval to see if there
is a more detailed map available for the area you are traversing, you don't actually have
to leave the current map - this is magic.
- You can now specify the datum for the blank map in the configuration screen.
- Thanks to another user there are some additional symbols on the web page for marine use.
- NMEA can now be read from other talkers not just GPS receivers and various bugs
Beta 3.60a (Developmental)
When you load this version, you will notice that it looks exactly the same as the last
version. There have been no changes to the look of the software this time, but there are
new menu options and configuration settings and heaps of changes, some subtle some major.
The new calibration methods (up to 9 points) are quite complex mathematically and could
be regarded as experimental.
The same also applies to the map projection and grid systems now supported, they have
had limited testing.
There have been many complex changes in this version so there must be bugs, please
report any problems and I will fix them ASAP.
There are changes to the OziExplorer GPS datum settings and the Buad rate settings,
there are now 2 of each, please check and modify these using the Configuration
option on the File menu.
I have changed the way I do the automatic changing of maps when doing moving map
(yes again). You will need to load and save all maps you use for Moving Map (load the map
and then press the Map File button which is located on the right hand side under
the button bar - this will save the map and write the necessary new stuff).
- The problem with Garmin route creation should be better, but I have not entirely solved
this problem to my satisfaction.
- Printing 256 color Grayscales fix.
- Color display for 256 color mode has been fixed and improved.
- Better trapping of errors.
- Unable to save the "Scroll Method" on the Navigation configuration screen -
- Magnetic Bearing was not being calculated correctly - now fixed.
- Many International Settings problems now fixed.
- lots of minor fixes.
- There are now separate Datum settings for GPS Upload/Download Datum and GPS NMEA output
Datum to cater for the many varying ways GPS receivers output their data. Please check you
- There are now separate BAUD rates for GPS Upload/Download and GPS NMEA output,
OziExplorer will automatically swap between the two when doing upload/download or Moving
Map (NMEA). Please check you configuration settings.
- There is a new route editor, allows you to point and select from a list of waypoints.
- You can now specify the size of the font for Waypoint display.
- The map objects (waypoints etc) should now always print at a readable size regardless of
the scale of the map.
- You can now hide any Map object (Waypoint, Event, Map Feature or Map Comment). This
allows you to access another object which may be hidden by another object or see what is
under the object. The objects are turned back on by selecting the "Unhide All Map
Objects" on the Map menu.
- When calibrating a map you can select from many different Map Projections and/or Grid
- You can now enter either Lat/Lon OR the relevant Grid coordinates when
entering calibration points.
- Up to 9 points allowed for calibration, based on the number of points entered the
software chooses which method to use for calculating the transformation coefficients. 2
points - linear method; 3 points - affine transformation; 4,5,6 points 1st order
polynomial; 7,8,9 points 2nd order polynomial (see the help file).
More points to come and hopefully selection of method and display of RMS errors.
- It is now possible to remove a point from the calibration without actually deleting it,
there is a checkbox for each point.
- As you select a calibration point tab, if there is already a calibration set for that
number the map will scroll to show the point.
- The calibration points are now shown on the MapView window
- You can now activate the MapView window from the Calibration window.
- Errors generated when a calibration is bad are now trapped and error messages generated.
There is now a help page for these errors.
- It is now possible to Import a complete set of USGS DRG maps in one operation, the
corner markers are also automatically set at the map neat line. You should now be able to
import a complete CD of maps and start driving with the maps changing at the neat line as
- Moving Map now has an arrow that always points in the direction of travel. Its a very
nice arrow available in any color as long as it is red. I will be providing more options
for the arrow in future versions.
- Now reads the $GPGGA and $GPVTG nmea sentences as well as $GPRMC, to allow for those GPS
units without $GPRMC. The $GPVTG is not tested as I do not have a GPS which outputs this
sentence, please let me know if it doesn't work.
- In Moving Map the Track now always joins completely to the arrow.
- Full onscreen Navigation assistance along a route using moving map, check out the Navigate
To ..... option on the Navigation menu..
- To aid in entering positions you can now specify in the configuration which country or
World Map Region you are in and the N/S or E/W will default to the correct choice.
- When calibrating points the zone number is automatically carried forward to the next
- You can now specify in the configuration if you want the map objects and zoom level to
be retained when loading a new map.
- You can now attach a waypoint and/or event and/or route file to the map (only 1 of each)
as well as any number of track files - this is done in the calibration options. The files
are automatically opened when the map is loaded (conditions apply related to the item
- When trying to open a map file if the map image cannot be found you are now asked if you
want to browse the disk to locate it, if you find it simply save the map to make this new
location permanent in the map file.
- Can download the Satellite Almanac from a Garmin GPS, not particularly useful for most
people but there if you want it.
- Many more zoom levels have been added.
- Zoom levels greater then 100% for TIF files have finally been sorted out and included.
The 75% zoom is missing for TIF files but is included for BMP files, there are technical
reasons why this is so.
- The calculation of screen coordinates from Geographic position has been speeded up, you
should see an improvement in plotting of Map Objects especially tracks.
- another map print mode - 4 pages wide
- I think that is enough for this version.
Beta 3.51c (Developmental)
- Fixed a bug where the track would not print in the correct place when the map was
zoomed. Also applied to saving the map as a bitmap when zoomed.
- When the mouse passes over a Map Object (waypoint etc) the zoom window now displays the
map underneath the object.
- Navigation (Moving map) has had many improvements (see the help
- Automatically finds and loads next map. Note : You must
load maps which have already been created by older versions of OziExplorer and use the
Check Calibration of Map option on the File menu to set up the new Moving Map
options, the maps will not be automatically loaded if you do not do this.
- NMEA GPS simulator
- Two methods of scrolling the map
- Adjustable Screen update rate
- Adjustable track update distance
- Adjustable Track tail length
- Proximity waypoints with alarm.
- Command line parameters to allow automatic starting.
- The Button bar now includes buttons for showing the Waypoint List and the Distance
between Waypoints Window. The GPS simulator can now only be accessed from the View Menu.
- When selecting the BNG grid in the Calibration screen, the Datum now defaults to
Ordnance Survey of Great Britian.
- Incremental Help improvements and Additions.
- Now also for Garmins, you can Send a single waypoint to the GPS by right clicking on the
- There is now the ability to download plot trails from the Lowrance/Eagles (Global Maps,
Global Navs etc) which only support protocol version 1. OziExplorer was not able to
download plot trails from these in previous versions. The code was tested within test
programs but has not been tested since inclusion in OziExplorer, I do not have one of
these GPS units to test with. Naturally let me know if it does or does not work.
- There are additional Map Feature symbols available thanks to a couple of inspired users.
- The printing of Map Objects (Waypoints, Events etc) to a specific size when printed on a
map has not been completed. Many trials have been done but a acceptable solution has not
been found, should be ready for the next version.
- Arrow for direction of travel for Moving Map display, next version.
Beta 3.51b (Developmental)
- I was a bit harsh when trapping UTM & BNG coordinates when calibrating. I was
forcing them to a strict number of characters, however there are certain instances where
other lengths are still legal. This version checks for the number of characters but only
issues a warning.
- other minor stuff
- Not to sure whether its a bug fix or a change bit its major. The flickering that
occurred when scrolling the map has been eliminated.
- The amount of resources the software uses has been reduced from about 38-40% to about
29-30%, allows 2 copies of OziExplorer to be run together more easily without running out
- The software now traps the loading of Tiff files which have the incorrect number of
colors, only 256 colors or 256 Grayscale is allowed.
- There are now 5 choices for the size of the MapView window (registered versions). Right
click on the MapView window for menu. The selected size is saved to the ini file to become
- There is now an option to Import Waypoints from a text file, similar to the Garmin
"Get Waypoints from Text File" option. The file format is identical but there
are more import options. This will allow you to create waypoints in a text file using
NOTEPAD (cut and paste and all that stuff) and then import them into the program. They can
then be saved as a normal wpt file.
- Much better support (now about 90%) for large font display setting in Windows.
- You can now double click on a Waypoint in the Waypoint list to open its properties. You
can also highlight multiple waypoints and delete them.
Beta 3.51a (Developmental)
- When calculating the Magnetic Bearing between points sometimes gave a negative number.
- If you attempted to change a map calibration from say Degrees to UTM, under certain
conditions an error would result.
- Fixed a bug in the reading in of Routes from a file, it was not getting all the waypoint
data from the file, if you have been having trouble uploading routes to Garmins this may
fix the problem.
- NOTE NOTE NOTE - to drag and drop the
Map Objects (Waypoints,Events,Map Features and Map Comments) you must now hold down the
shift key at the same time. This was done to avoid accidential movement of these
objects, and to allow other programming changes.
- There is now the ability to attach tracks directly to a map, this means the tracks are
loaded automatically each time the track is loaded. This is useful for adding small tracks
to show the location of new roads etc (see the help file).
- Added Close Map option to File Menu. This is for users of TIFF files so they can close
the map and therefore the TIFF file (which stays open as long as the map is there) so they
can remove a CD to load in a new map.
- Added the ability to create thumbnail images for use in MapView when using TIFF files.
The use of thumbnails can be turned off or on, but thumbnail images are only created for
TIFF files greater than 2Mbytes in size. This is to reduce the map loading time for large
- The total distance for a track is now calculated and displayed in the Track Control dialog.
- Distance and bearing from a Mark on the Map or a Waypoint, Event or Trackpoint can now
be displayed using the new Distance & Bearing Display dialog. The accumulated
distance from many marks is also displayed. Very experimental (see
the help file).
- UTM and BNG coordinates are now forced to be a specific number of characters, 6 for a
UTM easting, 7 for a UTM northing and 5 for BNG coordinates.
- You can now specify a default symbol for the creation of waypoints.
- You can now control the timeout for the comm port data input. With careful experimenting
you can significantly speed up data downloading from the GPS (see
the help file).
- Major oops! When calculating the Magnetic Bearing between waypoints the magnetic
variation was being added instead of subtracted.
- When calibrating a map you could get a floating point error when selecting the
calibration points. This bug has been following me around for ages (kept coming back)
hopefully its fixed properly now, this part of the code is quite complex.
- The GPS Stop Transfer button window would sometimes not appear in the correct spot when
the map had been scrolled, now fixed.
- Minor bug where the old saved tracks would not use the correct color when reloaded.
- Distance and bearing between waypoints in the routes have been added in the route
- When calibrating a map you can now select a calibration point roughly with the mouse and
then use the cursor keys to move the point a pixel at a time.
- The zoom window as well as being draggable will now follow the main OziExplorer window
when it is zoomed, this is much better.
- Fixed bug in 4 point calibration method, was not calculating one of the values
correctly, the error was normally minor but could cause objects to be placed out of
- Added the handling of UTM coordinates that can now be generated from waypoint + in its
- Fixed a bug where the printing of multi page maps missed a pixel between each page.
- Fixed a bug where maps in NT4 printed upside down (pretty neat effort that one).
- There have been extensive changes to the internal handling of the map image, almost a
total rewrite. The rewrite was done to allow TIFF files to be handled using a disk paging
technique. This has resulted in extremely quick loading of the TIFF file and zoom levels
that really work. USGS DRG maps benefit from this change enormously.
- As part of the new image handling there is now the ability to scroll the map by dragging
it with the mouse (there is a new button on the button bar for this). Dragging can also be
done direct by holding down the control key and drag the map with the mouse. To allow the
Ctrl key to be used for dragging the Insert Track Point key has been changed to the Alt
- You can now pass the map name as a command line parameter, full path is required if not
local and .map extension is required.
- The zoom window is now draggable, simply grab with the mouse and move to any position.
- Multiple tracks can be plotted on the map by using the Track Control dialog, 3 tracks
can be placed on the map for the shareware version and up to 6 for the registered version.
- When the map is zoomed objects such as map features, events etc would not be added in
the correct position, this has been fixed.
- Fixed the problem where the zoom window would not work in calibration mode if a map had
not already been loaded at least once.
- If calibrating or checking calibration when the map is zoomed resulted in the
calibration point bullseyes not being plotted correctly.
- If a map had not already been loaded, calibrating a new map would not allow all actions
until the new map had been loaded from disk.
All these problems basically related to the same area of the code. I hope I have now
fixed them, but the fixes may cause other bugs and I end up chasing my tail, but I will
persist until I have them all.
- The sorting of the waypoints in the Waypoint List dialog had a small bug - would skip
some numbers if you had reserved waypoints set (it should leave the reserved waypoints
alone but in this case would not get the starting number of the normal waypoints correct).
- Fixed major bug when calibrating maps, if you had not already loaded a map, trying to
calibrate a new map would not place the bulls eyes for the calibration points in the
correct spot or fill the correct x,y coordinates into the fields, you were forced to do
this manually. This was caused by 2 variables not being set - they were on the wrong side
of a "see if a map is loaded" if statement.
- When calibrating maps using BNG coordinates you were not allowed to enter the
coordinates the 1st time through the calibration procedure. This was caused by the
"setup BNG coordinate" procedure being called before I had actually set the BNG
flag (very dumb).
- Trouble reading the 750 waypoints from the Expedition - could not go past 250 (the
- In the Waypoint list you can now display the position in Degrees or UTM by pressing a
- There is a new menu option on the View Menu called Distance Between Waypoints.
This allows you to specify 2 waypoints and the Great Circle Distance and Bearing and the
Rhumb Line Distance and Bearing will be displayed. Caution
: Do not assume these measurements are correct at this stage, they need additional testing
- To allow for above a new parameter called Mag Var (Magnetic Variation) is now
requested when calibrating a Map.
- The New fancy menu system was Right Justified in NT 4 (don't exactly know why) subtle
differences between Win 95 an NT. This has been fixed.
- More problems with the decimal separator for international users.The problems were with
printing of the waypoint and event list as well as moving map. The ones reported were
fixed plus some others as well.
- Printing the view window for normal and zoomed maps was not positioned correctly. This
has been rectified.
- Could not import USGS DRG maps from hard disk if the fgd file was set as read
only. This has been fixed. This has also fixed the problem importing USGS DRG maps
when using NT 4.
- Added a new GPS to the list called "NMEA only". This is for GPS receivers
which are not supported for upload/download of waypoints etc but can still be used for
"Moving Map" display. The GPS must output the $GPRMC nmea sentence. There are no
guarntees that any GPS will work for the "Moving Map" function as I have very
little ability to test other units. I have tested the software with a Garmin GPS 12 and a
Lowrance Global Nav 200.
- Improved the status line display for "Moving Map". See the Navigation menu
help for details.
- The function to merge waypoints from a Garmin GPS to the waypoints already on the map
has been added.
- The GPS simulator for Garmins has been added. The simulator is based on a GPS 12 but
will also work for other Garmins with a similar sized screen with or without symbols. May
still need a little work.
- An experimental "Moving Map" feature has been added, to provide real time
navigation, see the help file for details. I really do mean experimental
and not very well tested so far, still needs a lot of work.
- Map Features now do not automatically become a Waypoint. This is now an option on
the Map feature property dialog. This allows more flexibility in their use.
- An attempt has been made to remove a bug where some systems would generate a floating
point error when moving the mouse outside the boundaries of the World map. I cannot
duplicate the affect but have made changes which may eliminate the problem.
- Waypoints can now be sorted by Name in the Waypoint List dialog. This was done mainly
for users of Lowrance and Eagle GPS receivers which do not sort their waypoints by Name
within the GPS. Now it is possible to sort the waypoints (don't forget to save them after
sorting) and upload them to the GPS in sorted order. Note - relatively
- A bug has been removed where calibrating a new map would not change the name of
the map attached to the quick save button which is located on the right hand side just
above the map. Pressing the quick save button would overwrite the previous map used with
the new maps data (ouch!).
- It is now possible to save the position and size of the OziExplorer window so that the
next time it is loaded it will assume the same position and size.
- A bug has been removed when printing of the Waypoint and Event list. This was related to
the regional settings. If the decimal separator was not a dot (.) the software gave an
error and would not print the lists. This problem has now been fixed.
- The drop down menus have been enhanced with bitmaps on the options (just for looks).
- Context sensitive help has started to be added to the various dialogs, only a couple so
far, many more to be done.
- PRINTING OF THE BITMAP IMAGE OF THE MAP HAS BEEN FIXED. Yes after much searching
I found the correct technique for printing images using the Windows 95 API, and as usual
the fix was very simple. There are also many different ways of printing the map. You can
now print the current view window, the entire map on a single page, or the entire map on
- The new symbols found in the Eagle Expedition and Lowrance Global Nav 212 have been
I cannot say for sure that there were any bugs fixed but there have certainly been a
great number of changes.
Beware - The inclusion of the new features have caused many changes to be made to code
that had previously been functioning correctly, this could result in bugs being put into
New Features for 3.0
- The ability to upload and download routes for Garmins.
- The British National Grid has been added (registered versions only). If any users, who
have registered or would like to register, require the Irish grid I will also add it in.
- The Routes now plot on the map.
- There is now the ability to create your own track (plot trail) on the map and upload it
to the GPS (Lowrance, Eagle and Garmin). This has resulted in a major change in the way
tracks are now handled. Creating a track with a lot of points with the points set as
draggable slows down the screen display dramatically. If you want to see a Pentium 200
slow down create a track with 2000 points or more and specify the points as draggable.
However I have allowed all this to be turned off selectively so it does not interfere with
normal operations. For more detail see the Track section in the help file.
- The Waypoint Date and Time can now be edited. I cannot gurantee that this date and time
gets uploaded to the GPS. I know it does not for Garmins because I cannot get the Garmins
to accept it.
- The Map Features (the blue circles with numbers) can now have user selectable symbols.
The symbol library can also be added to by the user, simply add your symbol in the
specified format (a bmp file of certain size and layout) into the symbols directory and
the software will use them. See the main help file for all the details.
The 2 point calibration has been fixed, it would only work if point 1 was above and to
the left of point 2. Hard to believe this bug was not found earlier, just about everyone
must have been putting the points in this way.
The problem with some international users having problems loading the data files when
the decimal separator was set to a comma (,) has been fixed. However now if the decimal
separator is set to a comma you must now enter all numbers with a comma as the separator,
a dot (.) will not be permitted.
There have been many checks put in to prevent bad data from being entered and/or
processed to prevent incorrect map calibration. This has also been done in other areas as
New Features for 2.1
The 3 point calibration (for registered users) is now included. I have also included a
4 point method as well, this will use the 4th point to find an overdetermined solution
which should give better average accuracy. The software determines which method to use
based on the number of points you have entered. The help file gives a description of each
There are now more ways to display the waypoints on the map. With pointer, with
symbols, with comment, pointer direction etc.
For Garmin GPS receivers with symbols the software now supports the GPS waypoint
display format as well. This can be set individually for each waypoint. The symbol and the
display format are uploaded and downloaded from the GPS.
The Hu-Tzu-Shan Datum was requested to be added, this has been done. If anyone needs
other Datums not included just let me know.
If your GPS has more than 1 plot trail (Eagle Expedition) the software will now ask you
for the number of the plot trail you want to download. This feature is untested ( no
access to an Expedition, they are not available in Australia yet). You may need to set the
Number of plot trails for your GPS to 3 within the software configuration. The best idea
is to select any other GPS and then select the Eagle Expedition, this will reset all the
GPS parameters to a more correct set. After you have downloaded a plot trail you must save
it before downloading the next. Use different file names for each trail.
Many other minor improvements have also been done.
Dozens of Bugs have been fixed - too numerous to mention them all.
I imagine dozens of new bugs have been added in with all the new features.
These are some of the major bugs fixed.
The Comm port now gets closed when leaving program
Drag & Drop of Waypoints etc improved
Loading in the Waypoint files produced by Waypoint+ has had bug fixes - would not work
with DM or DMS setting and would not get comments - these have been fixed. Also now works
with the new version 1.7.01 of Waypoint+ which supports symbols.
The Help files are now closed when the application closes.
The Append Waypoints from file has had a bug fixed. It would destroy some of the
waypoints already on the Map.
The printing of the Waypoints list has been fixed and much improved.
The printing of the maps is still not real good. If you have a paint package which can
print better you could save the map as a bitmap image and print it from the paint package.
Paint Shop Pro 4 works well for this.
New Features for Beta 2
* Routes - these have only been included for Lowrance/Eagle Receivers at this stage,
still needs a little work.
* Blank Map - a blank map can be selected which is initially calibrated to cover the
whole world but will auto scale as data is loaded.
* Grid for the Blank Map - experimental at this stage - also works for bitmap maps but
not necessarily for those calibrated using UTM coordinates.
* Edit Position - the ability to edit the lat/Long position for Waypoints and Events.
* Configurable File paths - in configuration you can specify the paths where the Maps
or Data files are to be stored.
* Merge Events & Waypoints from the GPS - Registered versions only - Allows the
Waypoints or events downloaded from the GPS to be merged with the Waypoints or Events
already on the Map. Merge can be done by number, name or position. Absolutely necessary
for extracting those few extra waypoints you have added in the field without disturbing
the settings for the waypoints on the map which are already in the GPS. For Lowrance and
Eagle GPS at this stage.
* Info box - displays vital configuration information at the press of a button.
* Stop button for GPS transfer
* Datums - Registered versions only - Specify the Datum for the GPS, Map and the data
files. The software will automatically translate the lat/long position between datums. Be
cautious with this option if the wrong datums are specified the data will be translated to
* Map View - Registered versions only - The best new feature, provides a small map to
help navigate the large map.
* UTM coordinates - Registered versions only - Whereever a position is required it can
entered in UTM coordinate system if required.
* Print a list of the events - not particularly useful but its now there.
