Hi,<br><br>New to GRASS, and running native 6.3.0 on windows Vista.<br><br>I have downloaded some finished 3 arc sec SRTM data from the National Map Seamless Server in both GeoTIFF and ArcGRID format, however I am having troule in getting it to display as 3D. I imported it via r.in.gdal and this seemed to work, however when I first load the layer it shows in the map display as a single colour block. Clicking 'Map display fills window' seems to show the raster properly, however NVIZ still displays nothing.<br>
Use of the profile tool gives the error 'elevation range for selected raster is zero', and the query tool outputs '(Lat)|(Long)| |211' for any cell. The <a href="http://r.info">r.info</a> module shows a data type of FCELL and the correct map area and range of data.<br>
<br>Any pointers would be greatly appreciated,<br><br>Simon.<br>
