Photo-ID for Imagery
Ground Control Point collection suitable for Satellite and Aerial Imagery in Italy, before traveling north to survey GCPs in Switzerland, Germany, Denmark, and Sweden.
A Europe-wide project including 16 full countries and parts of 3 Scandinavian countries. The surveyor in the photo records a static GNSS observation in a remote Italian town in the Alps.
Photo-ID GCP for LiDAR
USGS LiDAR Control
(Equals FEMA RISK Flood Mapping LiDAR Control)
Ground Control Point has to be flat or uniform in slope, ideally far away from break line and in case of Non-Vegetated Vertical Assessment Points on a hard surface.
Paneled Survey Control
CompassData crews have installed and painted
Photogrammetric panels in various shapes and sizes across
the world.
Coordination with customers to install panels in the correct size and in time before the aerial acquisition is standard.
