This survey and DTM software provides a great solution for coordinate geometry, digital terrain modeling (TIN, DEM), importing from WMS service and much more. It is designed for Land Surveyors and Civil Engineers.
-Import points and calculate points from measurements (polar method of surveying)
-Make longitudinal and transverse profiles when you have 3D points and 3D polylines or TIN model
-Import raster image from a web geoportal
-Generate TIN (Triangulated irregular network) model from 3D points for DTM and calculating volume by defining the lowest or highest 3D point- you can calculate the difference of volumes
