Folks,
Yesterday I introduced Geocentric coordinate system support in
GDAL/OGR. This includes OGRSpatialReference support for geocentric
coordinate systems, the ability to looking them up from EPSG, and
the ability to translate them to/from PROJ.4 format so they can be
used for transformation. This is an example of a geocentric coordinate
system looked up from EPSG. (Note the root is "GEOCCS")
GEOCCS["WGS 84 (geocentric)",
DATUM["WGS_1984",
SPHEROID["WGS 84",6378137,298.257223563,
AUTHORITY["EPSG","7030"]],
AUTHORITY["EPSG","6326"]],
PRIMEM["Greenwich",0,
AUTHORITY["EPSG","8901"]],
UNIT["metre",1,
AUTHORITY["EPSG","9001"]],
AXIS["Geocentric X",OTHER],
AXIS["Geocentric Y",OTHER],
AXIS["Geocentric Z",NORTH],
AUTHORITY["EPSG","4328"]]
I think there will be relatively little need for this coordinate system,
but I would appreciate feedback from anyone using it.
