» Activities - Photogrammetry - Possibilities

Photogrammetry retrieves the required information through images and as result the time spent in the field and the costs are dramatically reduced. Its products are widely used in many applications such as cadaster, transportation works, underwater surveys and archaeological or architectural studies.


GeoAnalysi S.A. was the first company in Greece that passed to digital photogrammetry, acquiring in 1993 a digital photogrammetric station. Today, the company's photogrammetric department is staffed with highly trained staff and has the necessary infrastructure being able to provide high quality services and products.
