Hello,
I tried to process bathymetry lines with negative elevation and it just
worked in GRASS 7.0.1svn r65198 @Linux. Maybe try if it works with
coarser resolution or region subset to test if the data volume is the
problem, or if your version of GRASS really has problem with negative
elevation values. Also try to look if the input raster contains expected
values, if you did not check that already.
If the problem persists, post your findings with log of the commands you
used, your GRASS version and platform.
If it seems a problem of the GRASS module, and you are using a recent
version of GRASS, it would be better to fill a bug, instructions at
http://grass.osgeo.org/development/bug-tracking/

Dne 18.5.2015 v 16:47 Irantzu Alvarez napsal(a):
I am trying to create a DEM from a bathymetric contour lines. Contours
are in vector format and the elevation value is negative (integers).
To create the surface I have converted the contours in raster (v.to
<http://v.to> rast) and then I have used r.surf.contour, but It
doesn't work (there is no error but the resulting output rasteris
exactly the same as the previous one, without any interpolation).
This are my region settings:
g.region -p -a raster=contours@iiaa nsres=1 ewres=1
projection: 1 (UTM)
zone:30
datum:etrs89
ellipsoid:grs80
north:4818927
south:4791484
west:486512
east:601275
nsres:1
ewres:1
rows:27443
cols:114763
cells:3149441009
I need a DEM of very high resolution of a wide area. I am using a
computer with large capacities for it.
Could someone help me please?
