Identification of obstacles

Satellite obstacle identification

Using data from Earth Observation satellites, Ascend can create terrain models and identify large constructions and terrain penetrating the protective surfaces in airport surroundings.

LiDAR obstacle identification

Using data from airborne laser scanners, Ascend can identify and produce a compliant obstacle analysis. With the LiDAR data we can identify obstacles as antennas and powerlines.

Manual obstacle identification

Using the limitation surface management solution, airports can manually inspect the the surroundings with the ability to accurately determine, if an obstacle penetrates the protective surfaces. We recommend using the XXXXXX fo the manual observations.

Compliance

Protective surfaces must be monitored for obstacles. We can help you identify the best data available in your area or originate new data. The aeronautical data requirements can vary depending on local regulations. Contact us for more.

Public data

In many countries you will find free public LiDAR data. We can use this data to identify obstacles in your airport surroundings. We run the data in the obstacle management solution, and make the result available to you.

Obstacle identification layers

Based on the LiDAR of satellite data Asend develops Obstacle Identification Layers. The layers are visualized as red clusters in the map. By holding your cursor over the cluster, you can see the penetration. The layers are divided in to 3 groups:

  • Obstacle Limitation Surfaces
  • Operational Surfaces
  • AOC type A surfaces
