<P><FONT size=2>Hi,<BR><BR>I'm using processed SRTM data from <A href="http://srtm.csi.cgiar.org/">http://srtm.csi.cgiar.org/</A> the<BR>current release is Version 3, which was a great improvement from V1<BR>and 2 especially with 1/2 pixel shift, coastline boundary clipping and<BR>filled holes.<BR><BR>I would like to ask others on using this dataset in calculating slope.<BR> I now have a working GRASS database with SRTM imported (as integer).<BR> In running r.slope.aspect, do I need to do further pre-processing of<BR>the SRTM DEM? The 90m pixel size is OK for the purpose of the<BR>research.<BR><BR>cheers,<BR>maning<BR><BR>--<BR>|---------|----------------------------------------------------------|<BR>| __.-._ |"Ohhh.
