I have a raster at 30m resolution in which is nested another raster at 1.5m<br>
resolution. I want to average the 4 points in the center of the higher res<br>
raster (in [row,col] enumerating from 1: [10,10], [10,11], [11,10] and<br>
[11,11]) and assign this to the nesting cell of the lower res raster. Of<br>
course I want to do this over all cells in the raster, which is say 10x10.<br></blockquote><div><br>While you can do this with GRASS, I tend to do these sort of processes with python and GDAL/OGR. If you are interested, I have put some notes here:<br>
