Sub-centimetre GPS control for aerial mapping.
GeoSurv establishes photo control for photogrammetrists using sub-centimetre GPS systems.
Overview
What this service is and why it matters
Who it is for: Photogrammetrists, mapping contractors and organisations commissioning aerial mapping.
Photogrammetry depends on accurate ground control. GeoSurv establishes that control using high-precision GPS, either as marked points or as features identified and surveyed from aerial photographs supplied by the client.
Using GPS shortens the time needed to obtain control and to prepare plans.
