National Wetlands Inventory data for 1988. Each downloadable Winzip archive file contains a quadrangle downloaded from the NWRC site. The quadrangle data has been converted into ArcView shapefiles with Geomedia csf files added.

Sample Coastwide 2001 Image Census 2000 SF3 Tables
Summary File 3 (SF3) consists of 813 detailed tables of Census 2000 social, economic and housing characteristics compiled from a sample of approximately 19 million housing units (about 1 in 6 households) that received the Census 2000 long-form questionnaire. Any of these tables are downloadable as a Winzip archive with files in either comma-separated values (csv) or shapefile (shp) format for blockgroups, parishes, tracts, congressional districts, and zip code tabulation areas.		   Picture of 1:24000 or 7.5'index1:24,000 Scanned Topographic Maps
Also known as the 7 1/2 minute quadrangles or DRGs (for Digital Raster Graphics). For selected parts of the state, post 1998 DRGs are also available. (The downloader's index map shows these quads in a lighter shade of green.) For more information about the updated DRGs, click here.
 
Sample Coastwide 2001 Image Coastwide 2001 Scanned Images

Sample DEMLIDAR Data
LIght Detection And Ranging data. Elevation data with amazing accurarcy and very dense coverage. LiDAR data can be represented in many forms. Currently downloadable is the contour form (as shapefiles), the DEM form, the raw point form, and the edited point form of the LIDAR data. Breaklines used to generate the contours and DEMS are also available for the latest additions. Each quarter quadrangle has the four forms (and breaklines in hte latest additions) and associated metadata files stored in a Winzip archive for downloading. (Latest arrivals are now shown in a  lighter shade of green .)
