Aspen CRM Solutions delivers highly accurate topographical data to surveyors in the engineering, mining, and agricultural communities. We combine high resolution aerial photography with precision GPS data to generate georectified orthophoto maps, digital elevation models, and 3D point clouds. Our mapping technology is capable of generating resolutions of less than 2cm per pixel, with accuracies sufficient for 1-foot contour mapping when combined with ground control reference points. We utilize both fixed and rotary wing surveying platforms, and employ certified photogrammetrists and pilots with years of Unmanned Systems and aerial surveying experience.
