EPSG Database Update Mechanism for libgeotiff, GDAL, PROJ.4, and PostGIS

[Frank Warmerdam]

Folks,

I have fleshed out the documentation on the process for converting EPSG
database updates into a form used in libgeotiff, GDAL, PROJ.4 and PostGIS.
It is available at:

   http://svn.osgeo.org/metacrs/geotiff/trunk/libgeotiff/csv/README

Paul Ramsey is now attempting to follow these instructions to generate
updates.  I have granted him temporary svn commit access to metacrs to put
the results into the libgeotiff repository under my close supervision.

Hopefully this will be the first step on a process to improve this process,
or at the very least to break the me-bottleneck on getting updates.

Best regards,
--

Hello Frank . . .

CS-MAP now has an object (TcsEpsgdataSetV6, see csEpsgStuff.h) which provides a decent set to tolls for accessing the EPSG Data set.  It also relies on a copy of each of the 20+ tables in the EPSG database in .csv form.  I have always done this .csv extraction process manually.

Does your scheme convert all 20+ EPSG tables to .csv form?

Can you ask Paul to stash a copy of all 20+ .csv files someplace where I can get a copy of them? (I assume you are doing this for EPSG 7.1!)

Norm,

Currently it looks like I'm capturing 12 tables as operated on by the script:

   http://svn.osgeo.org/metacrs/geotiff/trunk/libgeotiff/csv/pg_to_csv.py

It would be easy to extend it to capturing them all though I don't really use
a number of them in libgeotiff and related tools.  The current csv files are
available in http://svn.osgeo.org/metacrs/geotiff/trunk/libgeotiff/csv.  I'll
let Paul notify this list when he has updated things, and to clarify what
version of the database he is getting.

We work from the Postgres dump of the EPSG dataset normally.

Best regards,
