Aerial Photogrammetry

Aerial Photogrammetry utilizes photographs to measure topography(ground elevations, contours, etc.) and planimetrics (streets & building locations, etc). These photographs have been historically taken from planes at altitudes of greater than 1000 feet. Recently the technology behind radio-controlled model aircraft aka “Drones” has opened the market to low-altitude photogrammetry. Kelley Engineering and Surveying is leading the professional community of surveyors by adopting the latest technology.

Why Use a Drone?
  • Economical – Lower Cost
  • Faster Turnaround – Two Day Turnaround on most jobs
  • Fewer Consultants
  • High Resolution Imagery
  • Less Ecological Impact by using far less energy than an airplane

DJI Phantom 4
The drone we utilize was released in March 2016 and is part of DJI’s flagship UAV line. Features of the Phantom 4 include GPS, GLONASS, multiple safety sensors that provide obstacle avoidance, 4K/30FPS video or 1080P/120FPS slow motion capture, approximately 30 minute maximum flight mission time.
