Hi! Markus,
I am using a mask so as to limit my operation. The only improvisation I
did was this time to run the set on Fedora14 as I have my dual boot
machine. Luckily I have now my r.cost raster built. But, before going
for that I reduced the SRTM altitude values to range between 0-255. So,
some economizing on bit size was possible.
But,
But, now I am stuck with a new thing and this is with r.walk. I am still
performing this operation on F14. But, there is a crash everytime. The
input rasters are the two one the same rescaled raster for base values
and r.cost generated raster for friction values. But, it is crashing
every time. I am not getting a headway. I need to generate a route
between two cities cross the Hindukush mountain ranges in Afghanistan.
Any, ideas to this issue. I am thinking of using r.slop.aspect raster
for friction values what do you suggest.
Thanks and regards,
Ambrish Dhaka

Ambrish Dhaka,
you need to check the region extent + resolution, probably
you are exceeding the available RAM if you are having too
many rows and columns.
Get the information with:
g.region -p
or the respective menu entry.

Ramon says,
I'm afraid I don't - but given the current situations, I'd suggest anyone
that could help would also be wondering which version of QGIS you were using
and on which operating system.
The Qgis version is 1.6.0 also, the result is same on GRASS (tcl/tk) 6.4
RC1, performed on WinXP SP3 on a core2Duo machine.

Hi All,
I am trying to create shortest path between two raster points (converted from
v.to.rast) and I use the STRM data for the input values between the two points.
This is the error I get.
r.cost input=afg_rast at user1 output=salroute start_rast=salang at user1
max_cost=0 -k
G_malloc: unable to allocate 524288 bytes at setup.c:64
Finished with error
Any idea why I am getting this?
Thanks and regards,
Ambrish Dhaka
