MapTap Data Buffet: make better maps

All of these data files require MapTap for PalmOS.
USA files are reduced resolution versions of data files from the US
Geological Survey's National Atlas. For the original data, in
standard GIS formats, see their web server.
Most of the original data was at scale 1:2,000,000, but has been
resampled to an even smaller effective scale for use in MapTap.
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).
City data makes use of population figures from the World Gazetteer (http://www.gazetteer.de/), (c)
World Gazetteer, used by permission.
The data manipulation is done
using the software tool FME, by Safe Software, a
batch-oriented GIS and file conversion Swiss Army Knife. The
translation to Mobile Geographics's internal MGV format is made with
custom tools running under the open source GIS GRASS.

Regular or VFS?
If you will be installing your mapfiles directly into your PDA's
memory, using a normal HotSync operation, we recommend that you use
"regular" files, which are organized in a way that will make your
HotSync operations as quick as possible. Once they're transferred to
your PDA, MapTap will unpack them for use automatically.
If you are installing your mapfiles onto a VFS expansion card (a CF,
SD, or MemoryStick as found on the Handera 330, TRG Pro, Sony Clie, or
Palm m500/m505/m515/i705/m130), then you should use the VFS versions
of the mapfiles. Place them on the VFS card, in directory "/PALM/Launcher", using
either the Palm Desktop software ("Install to card") or a standalone flash memory
reader/writer.
"Regular" versions of the files will not work on VFS. "VFS"
versions of the files can be installed directly to memory, but the
HotSync operation will take a very, very, very long time; it's
definitely not recommended.
If you don't know what a VFS card is, you probably don't have one.
Use "regular".

| US cities |
A collection of 35,000 cities and populated
places, separated into 4 files based on population (using 1998
best estimate). Includes
national capital, state capitals, and county seats. File breakdown:
- UScities1
- All cities with populations 100,000 or greater.
Also includes national capital, state capitals, county seats (even if
population is less than 100,000).
- UScities2
- All cities with populations 10,000-99,999, unless the
city is listed in layer "UScities1".
- UScities3
- All cities with populations under 10,000, unless the
city is listed in layer "UScities1".
- UScities4
- Populated places and other cities for which no
population figures are available.
