Photogrammetry from satellite data for volumes - Continental Mapping Consultants

Volumetric Mapping Using Satellite Imagery

Continental Mapping has recently produced incredible results on a photogrammetric mapping project utilizing stereo imagery from DigitalGlobe’s WorldView-1 satellite. Tasked to perform a project for an energy company that requires frequent volumetric surveys of its stockpiles, Continental Mapping, with partner eMap International, acquired stereo satellite imagery of the target area.

Even given the difficulty of photogrammetric compilation of a pure black coal pile, Continental Mapping’s experienced photogrammetrists were able to tie the imagery to existing control and produce 2-foot contours. An independent analysis by the client using aerial photogrammetric mapping showed Continental Mapping’s volumetric analysis was within 1% of the traditional aerial method’s results.
