We undertake three types of photogrammetric activities - simple photogrammetric interpretation using mirror stereoscopes, photogrammetric modeling using standard analytic stereoplotters (Zeiss Planicarts updated with optical shaft encoders), and digital photogrammetry where height information is extracted using autocorrelation techniques.

Our photogrammetric capability can be used for the creation of terrain models (DEM / DTM) from satellite imagery for telecommunications planning, through map revision and update (we have recently updated 1:25 000 for Ordnance Survey), to the creation of new mapping based on aerial photography.

Geo Strategies has the tools and experience for carrying out this work and we would be keen to assist you with your particular requirements.
