Terra Data has customized the United States Defense Mapping Agency's
Digital Chart of the World for use with Geocart. Digital Chart of the World
is a comprehensive 1 to 1 million scale vector base map of the world (over
800 MB of high resolution data). We have extracted all the vector data
and converted them into Geocart binary databases. To accommodate these
extensive data bases, Geocart 2.6's Lines dialog has been expanded. Thirty
separate line feature types are now supported.
The DCW data bases come on two CD-ROMs. There are eleven categories
of data:
- Cultural Landmarks, less than 1% all data
- Drainage, 28% to 42%
- Hypsography, 32% to 43%
- Hypsography (supplemental), 9% to 11%
- Ocean Features, less than 1%
- Physiography, less than 1%
- Political/Oceans, 3% to 4%
- Roads, 6% to 14%
- Railroads ,1% to 3%
- Transportation Structure, less than 1%
- Utilities, 1% to 2%
We also provide you with a tool that allows you to tame this enormous
amount of data. The included CropDataBase program allows you to extract
just the data you need so that Geocart will work with maximum speed.
