Rapid 3D Mapping
Rapid 3D Mapping is a technology developed by the Swedish defence and security company Saab. The system generates three dimensional maps by image captures of the terrain from a manned aircraft, helicopter and/or UAV. Rapid 3D Mapping makes it possible to generate a three dimensional map within hours of the flight, the results depends on the existing sensors available on the aircraft.
The typical coverage for an aeroplane is 100 square kilometers per hour with a resolution of 0.1m at ground level. Rapid 3D Mapping will revolutionize the field of geospatial intelligence and the way military and security forces get access to much needed accurately geo-referenced data. (Source: Wikipedia)
