Plane, Helicopter, or Drone: Which is Best for Aerial Photogrammetry?

Example of grade change measurements

For an aerial land survey, photogrammetry – the gathering of visual data via multiple overlaid high-resolution photographs – provides an affordable, fast, and easy method of acquiring large-scale survey data. Photogrammetric data can be acquired in multiple ways; the three most common platforms are planes, helicopters, and drones. Here’s …read more
