The Digital Terrain Modeling (DTM) collection is an integral part in creating sound and accurate contours at the desired interval.

IMC utilizes VrOne software to collect and edit the data. We collect many of the planimetric features as DTM. These features are supplemented by break lines and spots to accurately model the terrain. The operators can instantly generate contours to place spot elevations and QC the data while the stereo model is still in the instrument.

VrOne software is designed for mapping, it uses sophisticated smart algorithms that creates Triangulated Irregular Network (TIN) which connects all DTM points with gradated elevation lines resulting in an accurate topographic representation of the terrain.

A 3D rendering and visualization tool is also applied from different angles to QC the DTM data. Our clients receive a 3D DTM file that only contains the appropriate layers to be used as part of the TIN in the desired Autocad or Microstation format.
