UAV | UAS is part of the research infrastructure allocated at the Department of Geoinformatics – Z_GIS, University of Salzburg. In cooperation with the Department of Geography different topics in the field of unmanned aerial Remote Sensing are covered. In addition to traditional photogrammetric aerial surveying further focal points are monitoring projects, emergency management and also the field of integrating different sensors.

Surveying by means of unmanned aerial systems (UAS) allows the acquisition of a variety of up-to-date geodata. Currently, mainly aerial photographs are acquired and processed further to generate orthoimages and three-dimensional digital terrain models (DTM) with a resolution of single centimeters. This data and therefrom derived products enable very detailed analysis of the respective study area.

Applied hardware is a hexacopter (twinHEX, twins.nrn) with a calibrated, optical camera mounted (Ricoh GXR). Technical specifications of the UAS are provided below:

Technical specifications of the twinHEX  
Diameter 110 cm (incl. screws)
Weight 3.5 kg (without payload)
Flight speed up to 50 km/h
Payload up to 3kg
Mission up to 40 mins
Area (covered per flight) up to 0.5 km²
Transport removable amrs


Typical application fields for optical aerial surveying are:

  • Geography, Geomorphology
  • Archäology
  • Support in disastermanagement


During the AGIT Conference the UAS Summit will take place again. This key subject convents users, scientific expert audience as well as provider of UAV products for exciting dialogs and exchange.
