Create an accurate floodplain delineation from lidar points and determine estimated flood extents by comparing a water surface model and a ground surface model, created from highly accurate lidar.
In this example, we will show you how to:
This example requires ArcGIS 10.2 for Desktop software with ArcGIS 3D Analyst extension: Free 60-day trial
- Create a TIN water surface from water surface profiles
- Compare the difference of the water surface and the lidar bare earth surface
- Assess the floodplain delineation analysis
