I have a little piece of a big raster (image) and want to compare with the big raster. So that I
Is it possible with arcgis 9.3 (and arctools) to search the same pieces on de big raster
and export to a shape file. 
I think there are differents way for a solution.
Can I direct two images (jpg, tiff,img etc) with each other compare ??
Or have first convert the both raster files to a point or/and polygon files. ??
Which tools can ik used for it ???
