GIS Data Portals and GIS Map & Data Resource Sites -  Here is my listing of good gis data sites I have used in the past, there are many more digital data sites that are not shown here.   Most every U.S. county/city/town now has some sort of spatial data in their planning, roads, or gis departments.   This list just covers major sources of spatial digital data sites which I think would have a broad appeal.  If you find a site that you think  should be included, please e-mail it to me.   Also, visit my GIS jobs listing page at the bottom of this page. info @ cccarto.com
