The Survey Operations Group is responsible for establishing project-specific geodetic control, placement and survey of aerial photography ground control, and applications involving specialized field techniques or equipment, i.e. use of GPS receivers, high-accuracy leveling equipment and reflector-less measurement systems.
The Remote Sensing Group performs survey work to produce base maps, mosaic images and digital terrain models from aerial photography and other tools. Development of photography mission plans, flight paths and ground control plans is also available.
