Hi everyone,<br>
<br>
I'm getting troubles to run r.walk. If I run r.walk in this <b>region</b>:<br>
<br>
<blockquote><font face="monospace">projection: 3 (Latitud -
Longitud.)<br>
zone: 0<br>
datum: wgs84<br>
ellipsoid: wgs84<br>
north: 33:39:03N<br>
south: 29:16:03N<br>
west: 33:54:48E<br>
east: 40:34:24E<br>
nsres: 0:00:03<br>
ewres: 0:00:03<br>
rows: 5260<br>
cols: 7992<br>
cells: 42037920</font><br>
<br>
</blockquote>
the algorithm runs fine. <br>
<br>
But <u>isn't the region</u> I need analyze, when I <b>change</b>
into this other one:<br>
<br>
<blockquote><font face="monospace">projection: 3 (Latitud -
Longitud.)</font><br>
<font face="monospace">zone: 0</font><br>
<font face="monospace">datum: wgs84</font><br>
<font face="monospace">ellipsoid: wgs84</font><br>
<font face="monospace">north: 37:21:17.568N</font><br>
<font face="monospace">south: 25:06:44.82N</font><br>
<font face="monospace">west: 31:46:15.96E</font><br>
<font face="monospace">east: 43:23:24.576E</font><br>
<font face="monospace">nsres: 0:00:08.999949</font><br>
<font face="monospace">ewres: 0:00:08.999272</font><br>
<font face="monospace">rows: 4897</font><br>
<font face="monospace">cols: 4648</font><br>
<font face="monospace">cells: 22761256</font><br>
</blockquote>
The algorthym <b>stucks</b> in the <font face="monospace"><i>Calculating
cost</i></font> step. It's a widest area, in exchange the number
of cells has been reduce a lot.<br>
<br>
I'm running <u>GRASS 6.4.3 on Ubuntu 12.04</u>. I thougth this
could be due to a lack of RAM???. <br>
<br>
Can anyone help me??<br>
<br>
Thanks a lot.<br>
<br>
Luis.<br>
