[gdal-dev] OGRSpatialReference::autoIdentifyEPSG and the pcs.csv table

[David Strip]

After an admittedly quick skim of the code base, it appears that the 
pcs.csv file is used only to go from an EPSG to the parameters for a 
spatial reference. If my reading is right, then it is not used to go 
from a WKT to an EPSG. The autoIdentifyEPSG works for a few special 
cases, but otherwise relies on the presence of an authority node for the 
projection's EPSG. Is that correct? If so, that would explain my earlier 
question about the WKT for Maryland State Plane not being recognized 
even though it's in the pcs.csv file.
