Comparison of PhotoSat, LiDAR, Drone and GPS Surveying
For surveying situations that are not simple and obvious, the white paper identifies the factors that should be considered when selecting the best survey method. Seven factors are compared and contrasted for the four survey methods in the white paper.
This report lists all the recent accuracy studies conducted by PhotoSat and shows the relationship between ground control point density and PhotoSat survey grid accuracy for grids derived from photo pairs of the DigitalGlobe’s WorldView constellation. For detailed information on any of the studies, please see the respective report.
Comparison of mine Survey Offsets
PhotoSat WorldView-3 stereo satellite surveying accuracy study, Garlock Fault, California, 1 GCP, RMSE 13cm. A 1m grid of elevation values, covering an area of 150 square kilometres, was produced over a PhotoSat test area in California. See the full report prepared by Gerry Mitchell, P. Geo, Geophysicist, President PhotoSat.
Mining project survey errors: root causes and their solutions
This report discusses the root causes, the consequences, and the solutions for the worst mining project survey errors. The report describes mining projects in Mexico and Ecuador that had serious, costly, delays in their feasibility studies due to undetected survey errors.
Maximize tailings capacity and freeboard with PhotoSat surveys
Determining the remaining capacity of your TSF requires accurate and repeatable determination of the edge of the pond and high-density elevation measurements on the beach. Learn how to get consistent TSF survey data anywhere in the world.
