I would like to modify a raster (pixel values) in QGIS.
The plugins "value tools" can easily provide me with the value of the pixel of my raster. However I don't know how to modify it.
I have found the Q&A titled Is it possible to manually correct a raster DEM (OpenSource)? which says that it is possible to do it in GRASS. I'v spent several hours on trying to understand how grass works without success.
I can't find the d.rast.edit tool in the sextante plugin. Is there another way to acess it?
