Trimble Business Center Other features: georeferencing background image for Aerial Imaging, GNSS and

optical data postprocessing, GNSS site calibration, deliverables analysis such as

contour and profile line generation, volume calculation and cut & fill map

creation, integration with conventional survey & scan data, measuring photo

points, feature code processing, corridor creation, report generation, export to

CAD/Sketchup,...; all in seamless workflow (depending on licenses; photogrammetry

license features in bold)

Image analysis: vegetation and flood
