Floodplain Analysis

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:

  • 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
