Photogrammetry Photogrammetry is the art and science of collecting spatial information from photography and imagery. GeoMetrics provides fully digital photogrammetric services for a variety of applications. The first step in the process is the planning of the project with the Client. Once the size and scale of the mapping has been determined, GeoMetrics team designs flight lines for aerial photography.
Ground control is needed to scale and orient the photography.
The GeoMetrics experienced field crews lay targets which are visible from the air. The airplane then flies along the pre determined paths with GPs guidance. Aerial photography is taken and the position of the center of each photograph is recorded using GPs Additional sensors such as lasers and radar can also be synchronized with the photography. Most mapping is done using black and white photography. Other films such as infra red can be used for special projects.
