.yes it is possible to do the point cloud matching also for projects including satellite scenes with different resolution. As internally we generate epipolar images, the resolution of those will be the mean resolution of all satellite scenes.
TRSS is a combination of all inpho modules (MATCH-AT, MATCH-T, OrthoMaster, OrthoVista, DTMaster) + eCognition object based image analysis with a streamlined workflow exclusive for satellite images. The georeferencing part is able to triangulate satellite scenes with different resolution. In tests we have seen a positional accuracy improvement by a factor of 10 compared to the downloaded satellite data.
