[Gdal-dev] GDAL/OGR EPSG Upgrade In Progress

[Frank Warmerdam]

Folks,

This is a warning that I am in the process of upgrading the version of the
EPSG databases used by GDAL/OGR - notably OGRSpatialReference.importFromEPSG()
and OGRSpatialReference.SetStatePlane().  This includes an update to the
files in gdal/data, upgraded to the latest table, and substantial changes to
the code that turns the tables into WKT descriptions ... since the
relationships of the EPSG tables have changed substantially.  Previously
EPSG 4.3 tables were being used, but I am upgrading to 6.2.2.

Note, I am also re-implementing the port/cpl_csv support for CSV files to
follow the CSV standard (escaping of quotes is with paired quotes), and
changing things to keep the .csv files loaded in memory (and indexed) after
the first access.  This means that expanding multiple GeoTIFF definitions
should be much faster than it used to be.

While the upgrade is going on EPSG (and GeoTIFF PCS/GCS support) may be
flakey.

Best regards,

--
