One of the features of the software is the ability to display many different screens by paging through them. To change pages, use the main menu bar buttons "Next" and "Previous" . (Pages can also be changed by swiping across the bottom of the screen).  Each page has a theme, the default pages are listed below.

Note: the number / layout of pages may differ slightly for portrait and landscape and for different screen sizes.

Several pages may have a map and may have buttons on the map such as Zoom In, Zoom Out, Zoom %, North Up /Course Up, and 3D.

Page 1. Main Map - See the "Buttons on the Map" section above.  May also show parameters such as speed and the current map zoom.

Page 2. Moving Map - shows cursor position in the units configured in Configuration / Units, Satellite information - Hdop, Number of Sats and small SNR Graph, Speed, Heading and Altitude.

Page 3. Odometer - the page has one or more odometers, each odometer has a start / stop and reset button.  An odometer reset can have reset with confirmation Y / N.

Page 4. Waypoint Navigation - shows the parameters Wp name, distance and bearing to Wp, Wp ETE and ETA. The Nearest Wp List shows the waypoints in order of distance from the current cursor position. Approaching waypoints are shown in green. Buttons are provided to cancel navigation, show/hide waypoints, show the Wp List and Nearest Wp List. To navigate to a waypoint, show one of the lists and click on the waypoint. Select the Navigate To option from the menu.

Page 5. Route Navigation - shows the parameters Route name, distance remaining, Route ETE and ETA, next Wp and distance and bearing to next Wp, Wp ETE and ETA. Navigation buttons are provided to move to next / previous Wp, show route, show Wp names, commence forward  / reverse navigation, cancel navigation and load a route. To navigate along a route, load a route and press forward (or reverse) navigation. To skip a waypoint, press the Next button.

Page 6. Compass - shows a compass and parameters VMG, XTE heading, bearing to Wp Route ETA and Wp ETE.  The compass shows current heading (blue triangle), bearing (green arrow) to the next Wp (orange).

Page 7. Information - shows many parameters such as date, time, sunrise, sunset, memory, speed (avg and max), acceleration (min and max), altitude and climb rate.

Page 8. Profiles - profile graphs of speed and altitude.

Page 9. GPS Satellites - shows satellite graphic and signal strength graph, HDOP, and number of satellites the GPS is using for a fix and other general parameters. HDOP is Horizontal Dilution of Precision - a guide to the current accuracy (1 is good 50 is very bad).

The screens can be designed on the PC by using the "OziExplorer Android Screen Designer" program. This program can be downloaded from the OziExplorer Android page of our website.


Waypoints - there is a maximum of 10,000 waypoints.

Tracks - up to 25 user tracks can be loaded. The total track points for all tracks cannot exceed 30,000. To allow the maximum number of tracks to be loaded, the tracks are filtered using the Track Point Reduction Factor in Configuration / Tracks.

Routes - one route can be loaded.

Type of Maps Supported

OZF2 and OZFX3 are fully supported.

ECW are supported but zoom levels cannot go below 50 or 60% at this stage, we are working on the code for lower zoom levels. ECW is slow to use because of the high compression and the need to decompress the image page. The ARM cpu used by Android devices is not powerful enough for high speed ECW decompression. Even with the slowness ECW maps are quite usable for moving map.

PNG and JPG - for small images only (under 25Mbytes uncompressed size), the images must be fully loaded into memory. It is recommended these maps be converted to OZFX3 using img2ozf for use in OziExplorer for Android. The zoom for these images is restricted to 50 or 60% and above.

Working with Waypoints

Waypoints are stored permanently in a binary file and are automatically loaded each time OziExplorer is started.

Waypoints can be created at the current position.

Using the Waypoint List, waypoints can be edited and deleted.

Many OziExplorer waypoint files containing sets of waypoints can be loaded and are stored in the binary waypoint file. The waypoint files loaded are viewed in the Waypoint Set List.  Waypoint sets can be deleted from the Waypoint Set List.

Waypoints created can be exported to OziExplorer waypoint files for loading into the PC OziExplorer.

Waypoint Editing

Waypoint position editing is limited in this version but will be improved in later versions. The position can only be edited in Latitude/Longitude. The position is always displayed in degrees and minutes but you can enter the position in Degrees, Degrees and Minutes or Degrees and Minutes and Seconds.

Working with Tracks

Track Tail

The track tail keeps a temporary record of where you have been. The tail is only 1,000 points but can record a reasonable distance because of the "smart" logging of track points.

If you want to see where you have been over a larger distance then use "Log track to File" to keep a track for each day. The logged track can then be loaded as a user track to see where you have been

Track Logging (Log Track to File)

This can be turned on in configuration and logs track points to a file for each day of travel. An OziExplorer track file is created with a name based on the days date.

User Tracks

Up to 25 OziExplorer tracks can be loaded but there is a total limit of 30,000 track points for all tracks combined.

OziExplorer will automatically reduce the number of points in a track as it loads, a "smart" algorithm is used so the track will still essentially look the same but the number of points can be reduced significantly in most cases. The amount of point reduction is controlled by the "User Track Point Reduction Factor" in Track configuration. The default is 10, the higher the number the more points are eliminated. The aim is to reduce the number of track points loaded to keep performance at an acceptable level.

Individual tracks have a limit of 30,000 points - a track larger than this will be truncated, at this stage no warning is given if this happens.

To automatically load user tracks when OziExplorer starts put the track names in a file called "TrackLoadList.txt" and put the file in the "Data File Path" of OziExplorer. Each track file name is put on a new line in the file. Sub-folders of the "Data File Path" can be used.

The track files must be placed in the "Data File path" or sub-folders of the "Data File path".

examples entries in the "TrackLoadList.txt"
;example in a sub-folder

Modifying Page Files

Page files (which contain the screens) are created and modified using the Screen Designer which can be downloaded from the OziExplorer for Android page on our web site.

Do not modify the standard page files which are installed with OziExplorer, these will automatically be overwritten when a new version of OziExplorer is installed - you must give them a different name.

The standard page files are provided with the Screen Designer install and have "user" as part of the name, these can be used if you just want to modify to standard pages.

Waypoint Navigation

Navigation to a single waypoint can be done. Change to the Waypoint navigation page to have access to the functions and parameters.

To select a waypoint open the Waypoint List. Press on a waypoint in the list and select the "Navigate To" option.

Route Navigation

At this stage there is no ability to create a route in OziExplorer Android but routes created in PC OziExplorer can be loaded. Route creation will be done in a later version.

Change to the Route Navigation page to have access to the route functions and parameters.


Three odometers are available on the Odometer page. Using the Screen Designer you can place 1 or more odometers on any page.


Track profiles are available for Speed and Altitude - Distance is on the x (horizontal) axis.

The profiles use the data from the Track Tail.

The profiles need more development.

SMS position sending

OziExplorer can send and receive SMS messages containing position data from another device running OziExplorer.

The position from others is stored as a waypoint and updated as new positions arrive.

For now the SMS messaging system is controlled by a text file called sms_data.txt - the file must be stored in the OziExplorer/Data folder.

Add or modify the fields in this file to control the SMS messaging system.

Below is an example file.

;must be true for any part of the SMS messaging system to function

;name sent to others

;how often to send (minutes)

;do not send sms unless position changed by at least this distance (meters)

;put altitude in waypoint description

;send position parameters

;must be true for sms position to be sent

;list of numbers to send to (20 max)
;each number is a separate sms message



Modifying the Menus and Toolbars

The layout files (.dat) and the glyphs for the menus and toolbars (really just menus) are stored on the memory card in the "/OziExplorer/System Data" folder.

Do not modify the standard menu files which are installed with OziExplorer, these will automatically be overwritten when a new version of OziExplorer is installed.

Instead copy the folders of the menu or toolbar you want to modify to a folder called "/System Data/User Menus" (for menus) and "/System Data/User Toolbars" (for toolbars). OziExplorer looks in these folders first and will load these menus in preference to the standard set.

Note : you cannot add new menus or toolbars - you can only modify the existing ones.

The .dat file is a simple text file, there are instructions in the file for the layout.

There should only be a need to modify the "Main Toolbar".
