Subject [jira] [Commented] (SIS-117) Allow definition of custom CRS by properties files

Martin Desruisseaux commented on SIS-117:

Another source to take in account is the ESRI database:

However we need an easy for allowing users to provide their own CRS, because updating the
EPSG database is uneasy. One of the easiest way is to provide a list of CRS as plain _key_
- _value_ pair, where the _key_ is the code and the _value_ is the CRS in WKT (Well Known
Text) format. Such pairs can be provided in two ways:
> * As {{*.properties}} files
> * In the PostGIS {{spatial_refsys}} table.
> This issue is only about properties files.
> The above CRS codes are valid only in a namespace. The easiest way to specify the namespace
would be to use the name of the properties file. So a {{“”}} file might
define the CRS in the {{CUSTOM}} namespace.
> One open question is where (in which directory) to put those files.
