Post-Subsidence Contours

This command creates surface contours after accounting for subsidence. The surface is defined by prediction points which are POINT entities with the elevation of the surface. These points are then exported to the Subsidence Deformation Prediction System program which calculates the subsidence at each point. This subsidence output from SDPS is written to a DAT file in the SDPS directory. Post-Subsidence Contours then subtracts the subsidence values from the file from the elevation of the prediction points.
