      It is cosiderably smaller than yours, with 1m resolution the
      region is 5676x4142 pixels, but running r.surf.contour for 15
      minutes and still 0% done. Hope it is able to finish before I have
      to leave, I have common office PC. In any case I will let you know
      what was the result, you can try with the same data for
      comparison.<br>
      Looking at the data, which are of some inland water body, I see
      the most of the region area is covered by land, which is not
      covered by contours (there are contours for elevation <= 0
      only). Would see how the command copes with that, this could
      possibly be source of your problems, should your data also contain
      large areas not covered by the contours. It such case a mask may

          Thank you very much for all your support.<br>
          <br>
          I am using Grass 7.0 in linux and I am working in a high
          capacity computer.<br>
          <br>
          My bathymetry input file contains vector lines, and all of
          them have an elevation value, from -2 to -116, with an
          interval of  1 m. The file have 300 MB.<br>
          <br>
          After executing the v.to.rast command, I get a raster, and it
          seems that is correct (pixels have the value of the
          elevation).<br>
          I am trying to change te resolution in order to get the
          interpolation. If I choose a resolution of 1 meter, the output
          file is exactly the same as the previous one, but if I change 
          it (for example a resolution of 100 m), it works, but with a
          very bis pixexl size. The question is that I need a high
          resolution DEM.<br>
          This are the commands I have used:<br>
          <br>
          v.to.rast input=iso1@ras type=line output=ras_ir use=attr
          attribute_column=CONTOUR

                                  As you said, I think that the problem

                                  I would like to perform) the output
                                  raster has over 3 billion cells.
                                  Although I have a high capacity
                                  computer, grass doen't compute the
                                  surface.  With a resolution of 10 m my
