Hi Markus Neteler, yes, importing pixel values with r.in ascii and patch into existing into raster is simple easy for particular pixel, but if we want to assign a height value to more pixels, for example assigning height value to buildings in a particular area in raster map is difficult as we don't no to which pixel value we have to assign height value and checking each pixel value is difficult. And i am more intrested by doing automatic process.
Thanks in advance, nani.
