The map layer files you choose will determine what sort of maps you can make on your handheld. You can always add map layer files later, or delete files that you're not using.
The map layer files in this directory folder are the ones we think you will want first. The USA supplemental folder contains more detailed information for the USA: highways, railroads, smaller cities, county boundaries and names. You can install any of the files; they are grouped into a directories only for your convenience.
The -Zmap.pdb files should only be installed directly to your handheld, not to expansion memory cards like Secure Digital and Memory Stick. For files that will work on your expansion cards, use the files from the expansion card only folder, which have names ending in -Mmap.pdb. Or you can download the VFS Data Installer:
For best results, keep your frequently used map layers on your handheld in internal memory, and keep all of the map layers on your expansion card. MapTap Atlas will automatically use the version in internal memory if it's available, but will find the expansion card version if needed.
The MapTap data buffet has a list of all of the layers, how they were made, a picture, and a link to the original map data. From the Data Buffet you can download a single map layer whenever you need it.
Then you'll see MapTap Atlas's home screen. Tap "Draw" to draw the Digital Chart of the World.
When the drawing is complete, tap "Show..." to see the controls for your map.
Tap the "+" key a couple of times to zoom in.
Tap "Show..." again, and tinker with layer selections. You have your choice of city populations and other data.
Tap on the map near Corsica and zoom in for a better view. The "Thin?" checkbox shuts off names of smaller islands and countries, but you sometimes will want to turn off the thinning.
You can set the map window directly by tapping "Goto...". Then either enter the latitude and longitude of the center point, or choose a state or country by name from the popup list. Here's a quick way to get a map of Liberia:
Tap "Atlases" to go back to the home screen. If you then tap "US National Atlas", you'll see similar controls for the United States map.
Now you're ready to use MapTap Atlas.
World files are reduced resolution versions of the NIMA VMAP Level 0 data, formerly known as the Digital Chart of the World (http://www.nima.mil/publications/vmap0.html).
