of course it is possible – the only rule you have to follow is that you should do the georeference in the native coordinate system of the MODIS image. Practically. Hello, I have carried out a series of Georeferencing tasks in ERDAS Imagine for an assignment, however I did not record the type of georeferencing used. Dec 14, Assuming that I have a raster image (not georeferenced) and I have 4 control points (X,Y,Z), does Erdas have the capacity to georeference that.

This 3D model requires that GCPs are well distributed across the image horizontally and kn. However, using the z values should have helped constrain the model so checking the x,y coordinates prefereably against stand alone check points will show you the true accuracy of your georeferencing.
