Advantages of the OZF4 format for use with OziExplorer, OziExplorerCE and OziExplorer Android

Smaller size - The map is the same resolution as the original but is only 1.8 GBytes in size (original is 2.82 GBytes) which allows it to fit on smaller memory cards (for OziExplorerCE and OziExplorer Android).

Faster map scrolling - The 250K map has been converted to the OziExplorer map image format (ozf4) so provides faster operation in OziExplorerCE, OziExplorer Android and PC OziExplorer. This is particularly important in OziExplorerCE and OziExplorer Android where ecw map images are slow to read.

Improved North/South, East/West Scaling - The map has been reprojected to the Mercator map projection - this gives a more linear scale for different latitudes. The images below show a waypoint in Tasmania with a 2km proximity circle drawn around it, the image on the left is the original Natmap in the geographic map projection (Latitude/Longitude) and shows the distortion of the proximity circle. The image on the right is the map in the Mercator map projection, the proximity circle looks like a circle. Please note - the original Natmap works ok as the software knows about the distortion, its just a visual thing.
