Obstacles Surveying

The importance of obstacles surveying and the necessity to collect current and reliable geodata are ever-increasing in the aviation industry.


The importance of obstacles surveying and the necessity to collect current and reliable geodata are ever-increasing in the aviation industry. International regulations of ICAO require airport operators to regularly update the terrain and aeronautical obstacles data around the airport and in the approach and departure areas. This information is used to check the safety of aircraft approach and departure procedures and their compliance with existing regulations.
