[GRASS-user] DEM with bathymetric contour lines

[Irantzu Alvarez]

<http://gis.stackexchange.com/questions/146527/dem-with-bathymetric-contour-lines-in-grass/146658?noredirect=1#>

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 rast) and then I
have used r.surf.contour, but It doesn't work (there is no error but the
resulting output raster is exactly the same as the previous one, without
any interpolation).

This are my region settings:

g.region -p -a raster=contours at 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?
