Data Processing & Production

Digital Terrain & Surface Models

Terrain, surface and engineering models produced at the processing level, resolution and geometric complexity required for design, hydrology, analysis, visualization and downstream modelling.

What we do

Terrain and surface models matched to accuracy and geometry

MapSoft produces DTM, DSM, TIN, grid, contour and project-specific 3D surfaces from LiDAR, photogrammetry, field survey and existing topographic data. Processing depth is selected according to vertical-accuracy requirements, terrain complexity, output resolution and the role of the model in engineering or analysis.

Automated ground classification supports efficient production, while high-accuracy models can add manual ground correction, stereoscopic breakline mapping and field-measured detail. Outputs can be delivered as raster or TIN-based surfaces, including true 3D representations where inverted or multi-valued geometry cannot be represented reliably by a conventional 2.5D model.
