Willkommen bei
Vermessung AVT

Vermessung AVT-ZT-GmbH offers services in the fields of mapping, cadastral surveying, engineering geodesy, aerial and terrestrial photogrammetry, laser scanning and geographic information systems. Together with our subsidiary AVT-Airborne Sensing , AVT carries out photo flights in Europe and uses the images to model the terrains, alpine environments and cities and to produce orthophotos with ground resolution up to 2 cm.

The subsidiary IDC EDV GmbH covers the hardware and network support in AVT, and is also active in GEOSI surveying software sales, tourism marketing and CAD sales for BricsCAD.

Regional presence, international projects, customers caring and technical innovation are the cornerstones of our company policy. The company was founded in 1970 in Imst (Austria) by Franz Markowski and grew following the innovations and new users’ needs. Since 1999 the Vermessung AVT has been certified according to ISO 9001 standards. Currently, some of the management has been transferred to the 2nd generation of the families involved.
