OPK Surf

Automated digital terrain model and surface extraction

OPK Surf is an automated terrain and surface extraction environment providing highly precise digital terrain models (DTM) and digital surface models (DSM) derived from aerial imagery.

Intelligent multi-image matching through on-the-fly selection of the locally best suited images for DTM generation.
Extremely dense point clouds by using feature-based and least-squares matching techniques, with different strategies for DTM and DSM extraction. 3D Point extraction produces optimized 3D models by dynamic filtering of sensor noise.
OPK Surf is a part of OPK photogrammetry suite including several cartography software.

Point clouds, DSM and DTM are all GIS data compatible with most common geographic information systems (GIS).
