[GRASS-user] Stereoscopic images

[Morten Sickel]

I am involved in a project using aerial photographs, earlier we have
been using dias and an 'old fashioned' stereoscope for interpretations.
Now we are to get the pictures as files. What kind of hard- and software
do we need to view stereoscopic images on screen? Is this possible
within grass / ossim or otherwhere in the free software family? Do we
need to get some special hardware, or is is possible to calculate the
heightinformation from a couple of georeferenced images and then use eg
nviz? Does anyone here have any experience on that kind of work?
