Cannot retrieve EPSG authority from stateplane projections via via PRJ name

[christapley]

e.g.:

OGRErr eError = oSRS.ImportFromESRIStatePlaneWKT(0, NULL, NULL, 32767, "NAD_1983_HARN_StatePlane_Alabama_East_FIPS_0101"));
oError = oSRS.AutoIdentifyEPSG();
// oError == 7

We have modified the relevant .csv files so that EPSG Authority tags are present for the projections that have EPSG definitions and with that change the code above works.

Please see the attached files.

Thanks!

I'm not completely convinced this is a good idea to add AUTHORITY EPSG for ESRI specific codes... And when comparing to the current files, it seems you have added done many other changes than just adding AUTHORITY. How has this file been generated ?

Hello,

It was only added for CRS's that have an EPSG code defined. As users of GDAL we find this behavior more useful. The ID was also changed to match the EPSG. We thought this was the convention (e.g. pcs.csv). If this is not I can change the ID's back so the only thing that changes is the additional EPSG authority for relevant CRS's.

Thanks,

Chris
