Lab 6: Terrain Analysis

Deliverable 3: This map shows volume of sand change (in detail) by using both pre and post DEMS. The pre_Hurricane_DEM is subtracted from the post-Hurricane_DEM using the Spatial Analyst raster calculator to see the volume change. This is more detailed then the Cut/Fill map shown in deliverable 2.

Deliverable 2: This is post hurricane Ivan DEM for the study area showing the volume of sand eroded during the storm. The Cut/Fill tool from surface analysis in 3D Analyst tools is used for the volume change calculations. Red areas showing the gain and blue areas indicating the loss. The total volume change for the entire study area is 25467.189874 cubic meters.
Deliverable 1: It is pre Hurricane Ivan LIDAR image, covering University of West Florida property and a portion of Gulf National Shores area . The total amount of sand above the '0' plane in the study area is 1717118.08 cubic meters.
