Flight service

Flying is carried out in collaboration with the Swiss Air Force. The Aerial Photography flight service plans and coordinates all flying requirements.

Aerial photography is made for the following purposes...

  • updating the Topographic Landscape Model (TLM) and the national maps 
  • the orthophoto mosaic (SWISSIMAGE) 
  • orders from the Federal Administration, cantons and privates


In addition the aircrafts are available for use as platforms for special flying requirements such as laser scanning or airborne gravimetry.

Our Services

  • Flight planning and offer the flight costs 
  • Comprehensive advice on matters such as optimal use of the digital sensor ADS100 and optimal timing for weather and vegetation conditions 
  • Coordination and implementation of all aerial operations in cooperation with the Air Force 
  • Processing of the trajectory and image control after the flight

Two powerful twin-engined aircraft are available to meet a full range of requirements in Switzerland and abroad.
