Katrina Water Levels

Katrina Water Levels
This image is a lidar elevation data set. This is important because geospatial based inundation maps and products can be quickly generated for response and recovery efforts immediately following the storm. GIS data sets can aid significantly in disaster relief projects, like the many that occurred in New Orleans after hurricane Katrina.



This next image shows the change in water levels by volume per feet-acre.




​

This map provides an estimate of the water levels of New Orleans from Katrina in the days following the storm. Since there is a significant level of spatial detail and vertical accuracy of elevation measurements, lidar is an important technological tool for use in low-relief hurricane-prone coastal areas and could help prevent further flood crises.
