[mapserver-users] New to Mapserver

Mon Feb 11 12:14:20 EST 2002

Steve, Thanks for your help. I have downloaded shapefiles from 
http://www.census.gov/geo/www/cob/st2000.html which are state boundary 
shape files. I tried to tweek the demo to work with that data. But I 
don't see anything on the maparea. The shape files are like st01_d00.xxx 
. There are three files per state. The following are my files.
