This tutorial should use the example stereo data available from Digital Globe.
This chapter is targeting researchers and the professional community. It should be okay to use technical terms that might be confusing to the layman.
I compared non-map-projected and map-projected stereo outputs, and doing map-projection improves the results quite a bit. Talking about run-time is kind of premature then, quality comes first.
I did not document yet sparse_disp as it is not yet officially released.
I added documentation about stereo_mpi, dem_geoid, dg_mosaic, as well as updated and expanded the relevant parts of documentation relevant to these features.
