[GRASS-user] filling inter-contour area with constant value

[Venkatesh Raghavan]

Dear All,

We are trying some morphological DEM interpolation algorithm which
requires rasterized contour maps with constant values in intercontour
areas. For example I like to fill the area between 10 and 20 meter,
20-30 meter vector contour lines with 15, 25m as constant value and
save the output as a raster map.

Is there an easy and fast way to do that in GRASS? Filling contour area
using GNUplot [1] and exporting data as an image maybe one option,
but I am wondering if there is another way.

Best

Venka
