Dear all,

I have a so large image (43,000 x 18,000 pixels) and I need clip this image with a smallest one (1000x1000 pixels). I can read the second image using rgdal package. But the first image canĀ“t be read on my system because if memory limitation (I have about 2GB availabe).

So I would like hear from you if anyone have some suggestin in this regards. I have also ArcGis 8.6 ans Erdas 8.3 running on my system and I can read the largest file without problem. But I dont know how clip the large image to keep only those pixels that math to he smallest image coordinates.

kind regards, miltinho
