| NGS Compressed Data -
National Geodetic Survey data, compressed by the Tri-Service CADD/GIS
Center is available from their web site. When you click on the following
link, a map of the States will be displayed. Click on a State to download
a zip file containing the compressed data. Download the data to a
directory on your hard drive which is named the same as the two letter
State abbreviation. For example, download va.zip to a directory named ‘va’.
The reason for this is so that SEMMS will recognize that compressed NGS
data is present and will automatically uncompress the data.
