[Proj] Update of EPSG database to v8.4

[Mikael Rittri]

Dear Even,

Thanks for your e-mail and your efforts. A gdal_datum.csv for the latest EPSG version is very useful to me. So I downloaded it from the GDAL trunk, but I found an issue. 

Line 46 is: 

1067,Peru96,geodetic,"ITRF94 at epoch 1995.4.  Densification of SIRGAS95 network in Peru, consisting of 47 passive geodetic stations and 3 continuous recording GPS stations.",1996,7019,8901,1189,Geodetic survey.,"Densification of SIRGAS 1995 within Peru. Replaces PSAD56 (datum code 6248) in Peru.","Details taken from national realizations page of WWW.SIRGAS.ORG, confirmed by reports from IGN Peru.",OGP,"2011/03/20",2011.018,0,"D_SIRGAS-Chile"

Where the last entry, "D_SIRGAS-Chile", seems to be wrong. On the page 

http://resources.arcgis.com/en/help/arcgis-rest-api/index.html#//02r300000105000000

I found the entry

5373
GCS_Peru96
GEOGCS["GCS_Peru96",DATUM["D_Peru96",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]

and I interpret this as saying that the ESRI name for the datum of EPSG:5373 is "D_Peru96", not "D_SIRGAS-Chile". 

(A check with www.epsg-registry.org confirms that the GeogCRS with code EPSG:5373 is named Peru96 and has a datum with code 1067 that is also named Peru96.)

Maybe the new version of add_esri_column.py can be blamed for this? I haven't checked whether the error occurs in previous versions of gdal_datum.csv. 

However, I admit that generally, I found that your generated ESRI datum names were correct more often than my own current effort. Well done! 

Best regards,

Mikael Rittri

Hi,

I've followed the update process of the EPSG SRS database to latest v8.4, and 
just committed the updated files into libgeotiff, GDAL and PROJ trunk. Also 
submitted to PostGIS.
