The problem is that I have one GeoTIFF input as the thematic map, and the referenced input is in a .shp file. Converting the .shp file to a GeoTIFF seams to be problematic. Is there any way to use the r.kappa operator with the .shp file as second input? Or maybe you have other ideas how to overcome this situation.<br></div><div><br></div><div><br></div><div>Thanks in advanced,</div><div>Danut</div></div></body></html>
