Tom Arnold commented on TEIID-3302:
-----------------------------------
After emailing with the maintainer I think proj4j is the way to go. Hopefully I'll
have some time later this week to take a shot at this.
Proj4j is not in Maven central. It seems like there's a couple of options:
* Upload it to central. Is this something the "official" upstream has to do, or
can anyone do it?
* Submit JIRA to proxy into JBoss repos.
Any advice?
Implement ST_Transform

Issue Type: Feature Request

Labels: spatial
Implement [
ST_Transform|http://postgis.org/docs/ST_Transform.html] system function. This
would be used to transform geometry between different coordinate systems. This needs
SPATIAL_REF_SYS table and a supporting library.
There are a couple of options for implementing this:
*
http://trac.osgeo.org/proj4j/ - Port of the C library used by PostGIS. Fewest
dependencies and should keep us close to PostGIS in capabilities. There will be a little
boilerplate to interface with JTS.
*
http://docs.geotools.org/latest/userguide/library/referencing/index.html - GeoTools
referencing module. I think we would need to develop a simple plugin to interface with our
SPATIAL_REF_SYS table. GeoTools is active and has good docs, but brings in a lot of
dependencies.
