At present, we are trying to automatically record the new use of land by buildings by systematically comparing aerial photographs (e.g. 2007 farmland -> 2008 warehouse). For this purpose, high-resolution aerial photographs are available every year since 2000 as WMS service.
Is there a plugin for QGis or ArcGis that could help here? Or is there another tool that you can buy for this purpose? Has anyone done something similar before?
