[GRASSLIST:8529] Grass & Aster DEM Creation, Any Possiblities?

Hi all,

I have an area (can't say where in the world) and we would like to have a good DEM. The 90m SRTM is too coarse. We have bee digitizing the crappy quality 1:25,000 scale topos but that is not fun and Raster2Vector is not very feasible becuase of said quality.

I was wondering about the possiblities of using GRASS to create a 30m DEM from Aster imagery. Any thoughts on the matter?
