Photogrammetry

Possibilities | Experience

GeoAnalysi S.A. has a longtime experience in this field as the company has already done a lot of of aerial and terrestrial photogrammetric projects.

Moreover, it has extensive experience in aerial photography with UAV and in the production of large scale orthophotos for archaeological sites. Considering the field of terrestrial photogrammetry, it has undertaken numerous projects for the production of orthophotos and the architectural documentation of important monuments.

As a result of its experience, GeoAnalysis has developed important research activity which concerns terrestrial photogrammetric applications, Computer Vision techniques and industrial design. Indicatively, some of the photogrammetric projects that the company has completed in the past fifteen years are:
