WingtraOne: Importance of Terrain Following

Terrain Following is a feature in the WingtraPilot app that enables users to plan their surveys without having to worry about manually fine-tuning parameters such as flight altitude. WingtraPilot considers the terrain automatically during flight planning. Once the user indicates the desired area to be covered, the automatically generated flight paths will follow any undulations in the terrain.

The altitude graph at the bottom shows how the flight altitude is automatically calculated to take terrain into account once Terrain Following feature is activated

The user can simply activate the terrain following feature and indicate the area he wants to map. The WingtraPilot app automatically adjusts the flight altitude minutely to ensure the entire flight is done in safe altitude and with required Ground Sampling Distance. Without terrain following WingtraOne will fly every area on a constant altitude.

Advantages of Terrain Following :

  • Enhances the flight safety of the WingtraOne
  • Facilitates flying with constant altitude above ground
  • Ensures consistent GSD resolution
  • Prevents accidents and any unwanted incidents

How to Enable Terrain Following

First of all, check if you have the elevation data enabled. The elevation data can be enabled in the General Settings within WingtraPilot. Once it is enabled you can decide for every area to use it or not. If you use it, the height of every flight line is adjusted to the elevation of the terrain. Use the altitude graph on the bottom of the screen to confirm that the flight plan is safe.

When Not to Use Terrain Following

Keep in mind, that the elevation data is exposed to uncertainties and it might be outdated in fast-changing environments (e.g. quarries). For areas below 56°S and above 60°N no terrain data is available yet.
