I have gone through similar questions to mine here, but I didn't find a solution. Please help!
When cropping a raster image by using
r.mapcalc, I get a new image but the resulting image doesn't have the same resolution. I have used
r.resample in the outer raster map but is still different. I have tried to change the resolution using
g.region, and even though the resolution is the same, the image display is not.
Is there a way in grass to cut an image from the main raster image and keep the resolution unchanged?
Also, I have tried using zoom to choose the crop area and its works! but as I have to do the same with a lot of images and need to be precise (when zooming), so it is difficult and takes a lot of time.
How could I solve this? Many thanks!
