---------------------------------------
Summary: Allow definition of custom CRS by properties files
Key: SIS-117
URL: https://issues.apache.org/jira/browse/SIS-117
Project: Spatial Information Systems
Issue Type: New Feature
Components: Referencing
Reporter: Martin Desruisseaux
Priority: Minor
Coordinate Reference System (CRS) definitions will be provided by the EPSG
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
{{“custom.properties”}} file might define the CRS in the {{CUSTOM}} namespace.
One open question is where (in which directory) to put those files.
