The Southeast Louisiana Flood Protection Authority-East (SLFPA-E), formerly known as the Pontchartrain Levee District, utilizes the Louisiana Coordinate System of 1983 (LACS83) for much of its geospatial data and mapping activities. This system is a state plane coordinate system established to provide a consistent and accurate reference framework for surveying, engineering, and geographic information systems (GIS) applications within the state. It is based on the North American Datum of 1983 (NAD83).
Employing a standardized spatial reference framework like LACS83 is essential for effective levee management. It ensures that spatial data from various sources, such as surveys, aerial photography, and LiDAR, can be integrated seamlessly. This integration facilitates precise planning, design, construction, and maintenance of flood protection infrastructure. The ability to accurately locate and monitor levee conditions, identify potential vulnerabilities, and coordinate emergency response efforts is greatly enhanced. Historically, the adoption of such systems has improved the overall efficiency and accuracy of infrastructure projects.
