Yes, Gdaltools includes a DEM (terrain models) option. You can find it at raster/dem. When you are working with the hillshading option remember to set th proper scale factor. If you are working with lat lon models <br>and your elevation is in meters , you have to set the scale( ratio of..) to 111120. If your coordinates units and elevations have the same measuring unit, in meters, scale factor is 1. <br><br>I prefer to us e Gdaltools because it can handle really large data sets with out a problem. For instance recentlye I produced a model of 2 degrees by 2 degrees and it did was not a problem for Qgis. I tried a doing just a 1 by 2 degrees with shaded relief plugin and.. your memory error appears.<br><br>Hope it helps<br><br>Gerardo Jiménez Delgado<br>Instituto de Investigaciones Antropológicas<br>Universidad Nacional Autónoma de México<br>Ciudad Universitaria s/n<br>Coyoacan 04510
