Subject: Images resolution and rectification.


I have an aster image.
Reading information on this kind of images: these are already projected in utm coordinates with 15m pixel resolution but are roted in the space for trayectory of satellite.
So I have imported it in xy grass envirnment and rectified it with the four utm coordinates readed from data associated with images.
The results is a good registration of image but a lost of resolution 15-->20m pixel.
There is a method to mantain the resolution of the image??
Many thanks Giorgio.
