Aerial survey is a method of collecting imagery by flying cameras or other sensors over a survey area using airplanes, helicopters or UAVs. Aerial surveys are necessary for a vast variety of applications including topographic mapping, forestry ground and canopy measurements, powerline corridor mapping, Digital Terrain Model (DTM) generation, high-resolution digital imagery, orthophoto production, and many more.
Airborne mapping can be expensive. The cost of establishing a network of ground control points alone can be prohibitive, as can the cost of running an airplane.
Applanix systems use Direct Georeferencing to reduce or completely eliminate the need for ground control points and fly projects more efficiently with less sidelap, greatly reducing costs and environmental impact.
Applanix' POS AV is a hardware and software system specifically designed for Direct Georeferencing of airborne sensor data. By integrating precision GNSS with inertial technology, POS AV enables geospatial projects to be completed more efficiently, effectively, and economically.
Applanix' POSTrack tightly integrates the POS AV Direct Georeferencing technology from Applanix with the XTRACK Flight Management System (FMS) software from Track’Air, in one compact ruggedized system.
