Create height map out of map with contour lines?

Recommended Posts

Is there an easy way to create an hight map from contour lines?

I mean, i have a map with contour lines but i can extract them, so i have just contour lines on white background.

Is there an easy way to do that? Or also a not soo easy way?

And, i mean create a heightmap out of something like that:

(And fuck i'm sorry, i asked that already at another (really old.../and at wrong Forum) Thread - wrong thread. I'm really sorry about that...)

Extracting heightmaps from contour data can be tricky, depending on the quality of the contour data available. Vectors are generally neat and clean, raster images often need tidied a little.

Most decent GIS programs will offer some kind of "contour trace or convert" option... You could try Qgis, which should be able to run the GRASS contours plugin, or maybe Kosmo, another free GIS program.

Here's an example contour > DEM tutorial for Kosmo...
