The topographer system is designed to create contour maps and 3D surface models from raw X,Y,Z data. Data may originate as surveying data, USGS data, or be generated by the user. Also, once an existing and proposed model has been created of a particular site, it is possible to perform cut and fill calculations.
Create quick, easy and accurate contour lines automatically
Create 3D Terrain models from your contour data. Models
may be either "mesh" or "cake" types.
