Preparation of geodetic situational plans

A geodetic situational plan is a graphic representation of the terrain and its content in horizontal and vertical sense in an adequate proportion.  It encompasses all natural and artificially created entities inside of a defined scope, shown with characteristic points.  

The confiruation of the terrain is presented by elevations and isoheights with determined, proportionally adapted equidistance.  In digital geodetic situational plans, the configuration of the terrain is defined with Digital Terrain Model (DTM), and it usually consists of Triangular Irregular Model (TIN).
