Task

Flight planning software packages often use low resolution DEMs without trees or buildings. By bringing flight path into GIS and using latest high resolution DSMs we can make sure flight path will not cross any obstacles.

Analyze and visualize:

  • flight path altitude
  • flight path height above terrain
  • check for any obstacles

Flight altitude

Height above terrain

Flights with different GSD and overlap

Yellow flight has GSD 4 cm, blue flight has GSD 2.4 cm
