[Mapserver-users] how to hide water areas in nationalatlas state-boundaries shapefile

[Brian Fujito]

Thanks for the tip!  I ended up using your suggestion, and it worked 
perfectly. So others in the future know:

1) start with the statsp020.shp/.dbf information from Nationalatlas
2) Load that into JUMP (www.vividsolutions.com/jump)... i had to use
   Windows for that... didn't work on my Linux installation
3) Load Dataset -> statsp020.shp file (as ESRI shapefile).  That'll pick
   up the corresponding .dbf file as well (in same directory)
4) Make sure that dataset is "Editable" in JUMP
5) Edit->"Editing..." to open the editing dialog.  Click the "Select
Parts" button in there.  Then select the regions that you want to
remove.
6) Save the dataset.

... worked like a charm.

thanks again for your help.
