Topographic Differencing


1 differencing tool available for dataset: 2019 Ridgecrest, CA Pre-Earthquake Digital Surface Model. Please select a tool for differencing high resolution topography:

Vertical Differencing (start with raster):   Start Differencing  
Description: Subtraction of Digital Elevation Models (DEMs) beginning with raster data. Typically, this works faster and for larger datasets than the point cloud option. This tool also differences Digital Surface Models (DSMs) and Digital Terrain Models (DTMs).

Applications: Geologic and anthropogenic processes including river erosion and deposition, earthquakes, volcanic eruptions, deforestation, and urban growth.
