  Sample NWI Map NWI 1988 Data
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. For more information about the NWI data, visit the NWRC site at http://sdms.nwrc.gov/pub/la/newla88.html

 
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.

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
Scanned color infrared aerial photography of coastal Louisiana for the year 2001 produced for the USGS NWRC. Approximately 3,000 frames were scanned, resampled at 300 dpi, and converted into jpeg format. The coverage does not include every scanned frame. The images are downloaded from the LACoast web site at http://www.lacoast.gov. To view the metadata file for this dataset, click here.

Also known as the quarter million quadrangles or DRGs (for Digital Raster Graphics). The images have the margins with all marginalia (scale, projection, etc.) The files that are downloaded are either Winzip archives or self-extracting exe files. Each archive contains an image file as a Geotiff and a ASCII world file.

 
Southern La. GAP overview GAP 1992 Data
Gap Analysis Program (GAP) data for 1992-1993. Each downloadable Winzip archive file contains a quadrangle downloaded from the NWRC site. The quadrangle data is a TIF with an associated TFW world file. For more information about the GAP data, visit the USGS NWRC site at http://sdms.nwrc.gov/gap/gap2.html
 

   
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 .)
