All,
I see reference to the NAVD88 grids. Are there any of the other vertical grids
available? If not, can and or how would one add, say, the hybrid GEOID09 grids?

Ben,
I appreciate this attempt to elucidate the current status of vertical and
geocentric coordinate support for OGR/proj.4. Indeed it was work that Frank had
been doing the past year or so before being snatched up by the Google. As
you've found out, it's not quite complete or thoroughly docume
Hi folks,
The issues of geocentric CS and vertical CS are distinct, but they are related
in an important way: Geocentric coordinates are not very useful to the GIS
world unless they can be converted to orthometric ("sea level") heights, which
involves a vertical CS.
Currently, the GDAL/OGR/PRO
