Photogrammetry is a method of using photographs to make measurements, specifically used for obtaining the locations of points on a surface. The technique itself is not new, dating back as far as the 19th century. Today, using high performance computers and advanced software we are able to produce three dimensional models of large areas and structures with high levels of accuracy
Volumes of stockpiles, excavations, embankments, and any other features that project from or depress below the ground around it can be easily found using UAV photogrammetry. On the left is an example of a stock pile. This pile was found to contain 7650 m3 of gravel. This area was physically mapped, post processed and results on volumes, orthomosaics and contour files were produced in less than 2 hours of work.
