[gdal-dev] Re: gdal_rasterize 1.8.0 options

Even,

Hermann might be right. From reading several sources:
http://gge.unb.ca/Pubs/TR46.pdf
http://www.manifold.net/doc/double_stereographic.htm
it seems that double stereographic is oblique stereographic as long as
the origin is non-equatorial or non-polar.
The actual denomination "Double Stereographic" seems to be a ESRI
by-product that refers to "Oblique Stereographic". However, ESRI's own
descriptions of these projections are, at best, vague.
