Support z dimension in RefineSensorModel GCPs for orthorectification
I'm working on orthorectification with open-source software. I tried the orthorectification of a QuickBird image and I got great results! I developed a simple qgis plugin to manage the gcps more easily. The plugin translate gcps collimated and saved in qgis georeferencer, translating them into the specific format x y lon lat.
I have a question about refinesensormodel, the text file containing the gcps must have the format x y lon lat, but it is not possible to insert the dimension z. In fact z is taken from the dem, are you going to add the possibility of giving it in the text file? It would be useful, because it would increase the accuracy of the orthorectification, from the GPS surveys return z in hight precision.
