I would like to know which georeferencing method would provide the best result for Himalayan region in-case of Awifs(Raw) to Awifs(master) georeferencing..

I have already tried polynomial transformation but it shows shift and doesn't match accurately..

I tried rubber sheeting though and it give me comparatively good results with good matching but I am not sure it may cause distortion too at places and also cut the image from the outer GCP points..

kindly guide me if there is any other method where image is not cut and still I get good matching with the master image..I use ERDAS imagine for above operation
