The tools follow the order of a real job, from planning to checking the data.

  1. 1Drone GSD CalculatorPick an altitude for the detail you need
  2. 2Drone Overlap CalculatorSet speed, photo interval and line spacing
  3. 3Area CalculatorMeasure the site from a KML or coordinates
  4. 4Drone Image Metadata ViewerAfter the flight, check GPS, RTK and camera data

Then turn the images into maps and 3D models: process them in Aeroyantra, free for 14 days →
