Background
Topographic data for Louisiana
Topographic data in Louisiana is produced by the United States Geological Survey, the Louisiana Geological Survey, and parish geographic information system offices. Using contour lines to represent elevation and landforms, these datasets describe regions including the Mississippi Delta, the Red River Valley, and the Gulf Coastal Plain. Programs such as the Louisiana Statewide Lidar Project and coastal mapping efforts from the Louisiana Department of Natural Resources provide elevation data for floodplain managers, civil engineers, environmental planners, and hazard analysts.
These datasets inform flood modeling, coastal erosion assessment, and infrastructure planning. Equator improves this workflow by providing three dimensional visualization of terrain, integrating multiple datasets, evaluating hydrology and slope, and facilitating collaboration across teams.

What is the source of Louisiana's topographic data?
Most official topographic data for Louisiana is produced and maintained by the U.S. Geological Survey (USGS) through the 3D Elevation Program (3DEP). This program uses high‑resolution LiDAR and other elevation sources to generate accurate contour lines, DEMs, and surface models. Some local agencies also contribute updated LiDAR and elevation data to supplement USGS coverage.
