In my previous posts, I explained how to pan-sharpen and then mosaic Worldview-3 satellite imagery. The final phase of processing the 'ortho-ready' imagery is 'orthorectification'. To orthorectify the Worldview-3 imagery I used a 2m resolution digital surface model (DSM) generated by Digitalglobe from a stereo-pair of Worldview-2 satellite images of the same area of Middle …

Where can you find free high resolution satellite imagery for your project, which is the best imagery and what are the issues with it?
Georeferencing a map of the pyramid complex of Djedefre, wrestling with inaccuracies, residuals and RMSE.
What makes georeferencing historic maps difficult and how does the process work? Here I georeference a problematic map of Abu Rawash, pyramid and cemeteries, Egypt.
Satellite imagery is very precise but can still exhibit parallax. This is a particular issue for georeferencing historic maps, demonstrated here with reference to the Giza Pyramids.
