As above, in at least one set of blank images I see the (c) watermark which comes through ok. Also with r.in.wms you can look in the $LOCATION/wms_downloads/ dir and see the raw download images before any client processing. all blank. > In other cases, adjusting the region parameters - zoom in to a smaller > area, and use a finer resolution - fixes the problem. I took your suggestion and tried zooming in some. Success! I would note that earlier when I was getting the blank image I did check the bounds layer's capabilities to make sure I was not exceeding the bounding box. So it seems to be matter of scale, not bounding box. # LL/WGS84 location SERVER="http://www.geodaten.bayern.de/ogc/getogc.cgi?"; g.region n=49:17N s=48:33N w=10:54:30E e=11:32:30E res=0:00:02 r.in.wms mapserver="$SERVER" layer=UK500 out=UK500_Bavaria.3 format=tiff then you get a map of roads, place names, cities, etc. (format=tiff looks more detailed than 8bit png, but png is way more efficient for empty files. shrug) #zooming in more, DOP layer (2m aerial photo) looks good: g.region n=49:12:02N s=49:04:20N w=11:03:26E e=11:11:42E res=0:00:01 r.in.wms mapserver="$SERVER" layer=DOP out=DOP_Bavaria format=tiff # and zooming even further the TK50 layer finally works # TK50 is a similar feature map to UK500, including contours g.region n=49:10:06N s=49:07:34N w=11:06:27E e=11:08:54E res=0:00:00.25 r.in.wms mapserver="$SERVER" layer=TK50 out=TK50_Bavaria format=tiff So yes, zooming helps. The DOP layer draped over SRTM data would look very nice. Hamish ps- I have just added an option in SVN to store the capabilities file when using the -l flag. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
