Highest accuracy

PhotoSat produces the world’s most accurate 1m bare earth elevation grids (DTM) with 50cm contours from satellite photos. Using our unique geophysical satellite data processing system, we produce topographic surveys with 4 times the elevation accuracy of conventional satellite elevation mapping. Our accuracies have been proven using tens of thousands of ground survey points for comparison. View our Proof of Accuracy Reports.

To achieve 20cm accuracy PhotoSat uses a unique technology and set of algorithms that were derived from oil and gas seismic processing. Find out more about our data processing methods on the Technology page.

PhotoSat satellite mapping benefits:

  • Engineering quality satellite surveys available globally.
  • Cost-effective alternative to surveying, LiDAR, and photogrammetry.
  • Simplifies the surveying process: no in-country presence or permits.
  • Minimizes the exposure of field crews when accessing hazardous or remote areas.
  • Custom formats and projections.

Accuracy & Ground Control

PhotoSat’s elevation grids have been demonstrated to have a relative vertical accuracy of 30cm RMSE, and a relative horizontal accuracy of 50cm RMSE over horizontal distances of 10km.

To achieve 30cm RMSE absolute accuracy, a minimum of three surveyed ground control points accurate to better than 10cm are required for areas up to 200km². For larger projects, we request one ground control point every additional 200km². In the absence of ground control points the relative accuracy specifications apply and absolute accuracy is expected to be better than 3m RMSE.
