What maps does it use and what on earth is a ground model?
The digital map data employed in the system is source independent as long as the file type is “.DXF” This is simply an industry standard drawing file used by all CAD (Computer Aided Design) and ground modelling systems for data transfer between them. The designed ground shape (sometimes known as DTM’s (Digital Terrain Models) or DGM’s (Digital Ground Models) comes from a ground modelling system, but because it is 3D data (easting, northing and height) for each point it often gets moved around within CAD. However it has been handled, so long as you receive a 3D DXF version of the site, along with any required map overlay, which might include buried services / building / roadways / existing site survey information etc, the Prolec system should display it.
