The LSU Center for GeoInformatics is the home of the Louisiana Spatial Reference Center; creator and host of Louisiana's NGS CORS network. LSU created C4G to focus on research and services in Geodesy and GeoInformatics; as a result C4G has established Louisiana's only Statewide GPS/GNSS Real-Time Network, C4GNet which is entirely funded by subscribers to the RTN.
Subsidence is the underlying culprit behind Louisiana's most insidious environmental problem: the continuing loss of our coast. In addition to being a world-class scientific topic, coastal land loss robs the State of 25-35 square miles per year due to both natural and man-made causes. Subsidence has also had the serious effect of disturbing the system of reference markers we use for surveying the elevations of levees, evacuation routes, coastal restoration efforts, etc.
