LA GIS CD Frequently Asked Questions Tuesday, May 16, 2000
What is the Louisiana GIS CD?

The Louisiana GIS CD is a two CD set that contains over 40 spatial layers of geographic data including a satellite image of Louisiana. For a full description in text form, click here.

   
From where does the data for the CD come? Data on the CD are the best publicly available spatial data sources. The CD is the culmination of several years of data development and assembly by sponsoring agencies, and was developed by Louisiana State University with funding from the Louisiana Oil Spill Coordinator's Office.
   
Who are the sponsors? The agencies listed below collectively contributed data, assistance, support, resources, and funding to the development of this CD. They are listed in alphabetical order by affiliation.
State of Louisiana, Baton Rouge
  • Applied and Educational Oil Spill Research and Development Program
  • Department of Environmental Quality, Geographic Information System Center
  • Department of Natural Resources, Geographic Information System Lab
  • Department of Transportation and Development
  • Department of Wildlife and Fisheries
  • Louisiana Geographic Education Alliance
  • Louisiana State University

    Federal
  • United States Geological Survey, National Wetlands Research Center, Lafayette, LA
    Private
  • Environmental Systems Research Institute, Inc., Redlands, CA
  • Intergraph Corporation, Huntsville, AL
  •    
    What comes on the CDs?
  • environmental, transportation, boundary, and geographic spatial data in raster, polygon, line and point format,
  • a satellite image of Louisiana,
  • fully compliant Federal Geographic Data Committee (FGDC) metadata for each data layer,
  • ArcView™ 2.1b GIS from Environmental Systems Research Institute, Inc.,
  • GeoMedia™ 2.0 GIS from the Intergraph Corporation,
  • tutorials that help for utilization of the GIS software and introductions to GIS concepts,
  • a satellite tour of Louisiana, and
  • a user interface that provides easy access to instructions and documentation, software installation, and tutorials.
  •    
    From where can I get the CDs? Ordering information can be found on the Louisiana Oil Spill Research & Development Program website at www.osradp.lsu.edu.
       
    Can I get the data online? Yes! Use "Search Atlas."
       
    What about the Oilspill CD previously released? Version 1, released in 1996, is obsolete and is completely replaced by this version.
       
    Can I use my own GIS to view the data? Yes, if your GIS can read ESRI shapefiles. Owners of later versions of ArcView and Geomedia should be able to read the files without problems.
       
    What if I do not have a GIS? The CD provides two GIS to use for displaying the data: ArcView and Geomedia. The CD provides instructions for installing either GIS. You do not need both GIS: you can choose between them. You are encouraged to try both of them.
    Note: the GIS software on the CD only works for Window-based PCs. Macintosh and Unix users must provide their own software to view the data.
       
    Is metadata provided on the CDs? Yes, fully compliant Federal Geographic Data Committee (FGDC) metadata accompanies each data layer on the CDs.
       
    Will there be revisions and updates to the data? Yes, as corrections and revisions are made to the layers on the CD, they will be updated on the Atlas site. Messages will inform users of revised data layers. Also, additional layers will be provided on the site as they become available.
       
    In what projection and datum are the data? The vector data on the CD is in geographic latitude/longitude coordinates (decimal degrees), NAD-83 datum. The raster data is in UTM zone 15 coordinates (meters), NAD-83 datum.
       
    What are the hardware requirements for using the CDs? Minimum System Requirements: Below are the minimum requirements to run ArcView or GeoMedia. Since there are very large data files on the CD, the software will run very slowly with this system.
