I'm taking a good look on RGDAL documentation, and looking for some tutorials and docs. My first need is: a have two rasters, one is an SRTM relief, and the other is a region file. I need to do some calculations with the SRTM data (max und minimun) for each region of the other raster. Can anyone give me a hint?
