Dear Users, I have a couple of raster maps (RGB PNG images) where I need to remove the red grid lines. What would be the best way to do this with Grass ? I thought about using r.mapcalc to turn the red pixels (RGB value 255 0 0) to NULL data and then use r.fillnulls to interpolate the NULL data. I now how to do this for elevation data, but how to do this with RGB data ?
Thanks for any suggestions !
