<pre>Anyway, I decided to install grass 6.3.0 on my pc but i have some problems (i will open another thread for this).<br>I think I will install linux ubuntu on my nb too, so can<br>use grass without cygwin.<br>About what Hamish said, the problem is in the elevation resolution?? Could use<br>the 6.3.3 script usinf elevation.dem instead of elevation.10m?<br><br>Thank you,<br>Roberto<br><br><br>Markus Neteler wrote:<br>><i> I made a test, it works (Linux box):<br></i>><i> <br></i>><i> GRASS 6.3.svn (spearfish60):~/grass63 > sh<br></i>><i> raster/simwe/r.sim.water/spearfish.sh<br></i>><i> projection: 1 (UTM)<br></i>><i> ...<br></i>><i> cells: 294978<br></i>><i> Preparing input maps...<br></i>><i> Percent complete:<br></i>><i> 100%<br></i>><i> Creating support files...<br></i>><i> Elevation products for mapset [neteler] in [spearfish60]<br></i>><i> E-W SLOPE [elevation.dem_dx] COMPLETE<br></i>><i> N-S SLOPE [elevation.dem_dy]

faster.<br><br><br>Hamish<br><br><br><br></pre><p>
