High resolution satellite imagery with Quickbird has reached a level of detail previously only achieved by aerial photography. MadMappers brings you a taste of what Quickbird is capable of, by means of an aerial view of the Victoria Falls at the border between Zambia and Zimbabwe (courtesy of Digital Globe). Resolution was decreased by 50% to 1m/pixel and calibration of the image  was achieved with OziExplorer using GPS waypoints collected by MadMappers. The Image was then oriented to true north using GlobalMapper.

Download Victoria Falls by Quickbird (1,3Mb), load it in OziExplorer or GlobalMapper and compare it with your own GPS tracklogs or vector data. Let us know if you agree with the calibration.
