Geographic Information System

GIS Layer Model

TERRA 4D is based on a 3D geographical information system. The Digital Terrain Model (DTM) represents a 3 dimensional elevation layer of the ground. Satellite imagery, current and historic aerial photos are overlaid. 

The system translates unstructured sensor and system data into structured data and displays it in a geographical context, offering superior real-time situational awareness. Operators of TERRA 4D PSIM solutions can fly through time and space having virtual “eyes-on-the-scene”.
