Automated EPSG database updade

[klokan]

Automate the update of the EPSG database to ensure the latest version is always indexed.

This to be discussed with people from IOGP (International Association of Oil and Gas Producers). Initial conversation has happen already.

Possible implementation via an automated crawling (in cron) on the epsg-registry.org - to check availability of the new database.

This code can be used to retrieve automatically the latest GmlDictionary.xml
https://github.com/geo-data/python-epsg/blob/master/epsg/service.py

Update: The whole code above degrades to a simple one download URL which can be used to get the latest version of the zip file:

It is:
http://www.epsg-registry.org/export.htm?contentType=WithEPSG

The automated update should also upgrade the libtiff / GDAL / Proj data, to be coherent accros the website:
