About Photogrammetrie – Vermessung Alexander Kühn
Photogrammetrie – Vermessung Alexander Kühn is a sole proprietorship based in Jena that specializes in building surveying and measurement, with a particular focus on listed historical architecture. The company produces 2D floor plans, sections, elevations, 3D BIM models, high-resolution orthophotos and 3D surface models in accuracy classes I–IV. Data acquisition is carried out with Leica tachymeters (1''–7''), FARO laser scanners (1 mm), drones and high-resolution Zeiss cameras with high-performance lenses. Using digital photogrammetry, hard-to-reach areas as well as structures with obstacles such as scaffolding or trees can also be captured without contact. Clients include private and public clients, planning offices and specialist authorities from architecture, construction planning, renovation and heritage conservation; results are delivered within two days of the survey.
