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. It has been supplemented twice.

What is in supplement 2 of the Louisiana GIS CD? The supplement, released as a DVD, contains recently released or revised geospatial data of Louisiana pertinent to oil spill prevention, contingency planning, response, damage assessment, and environmental restoration.
From where does the data for the CD and its supplements 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.
