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.


Quick jumps

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".
USA
US States
US state boundaries, with state FIPS codes, 2-letter abbreviations, and names. "USFIPSstateATR" is needed if you want to see names; without that file only the FIPS code is visible.

US counties
County/parish boundaries, with county FIPS codes, with county FIPS codes and names. "USFIPScountyATR" is needed if you want to see names; without that file only the FIPS code is visible.

SDTS
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.

US highways
Major roads of the United States, separated into 5 different files based on the road category. Categories are:
UShighways1
Limited access highways. A route that is part of the United States Interstate Highway System or other similar expressway.
UShighways2
Principal highways. A major United States-numbered highway or one of the most important State-numbered routes.
UShighways3
Other through highways. A major State-numbered route or a minor United States-numbered highway.
UShighways4
Other highways. A minor State-numbered route or other connector road.
UShighwaysF
Ferry crossing (across water).
Load only the files up through the lowest level of road quality that you need, but load all the lower-numbered files also; e.g. UShighways1, UShighways2, and UShighways3 must all be loaded to see "Other through highways".
