Is there any (photogrammetric or other) FOSS package to support the generation of a DEM from ASTER L1B products (i.e. combining the spectral bands 3N and 3B)? Are there any practical examples or/and tutorials? It would certainly be preferable if the tools in question integrate easily in (workflows implemented in) well known GFOSS GIS/RS tools.

Best Answer
Some time has passed, the topic is still relevant since new software became available:
Did anyone try out the NASA Ames Stereo Pipeline (ASP, http://ti.arc.nasa.gov/tech/asr/intelligent-robotics/ngt/stereo/)? The source code is on github.
Furthermore, in the open source software Orfeo Toolbox (OTB, http://orfeo-toolbox.org) they offer "One-click DEM generation" in their Stereo Framework (announcement). In the manual, there is a chapter on "Stereoscopic reconstruction from VHR optical images pair". Did anyone try Orfeo?
