Allow SLD geometry filters in a different SRS to the data layer, to be
projected on the fly as happens with WFS filters
-----------------------------------------------------------------------------------------------------------------------
Key: GEOS-4490
URL: http://jira.codehaus.org/browse/GEOS-4490
Project: GeoServer
Issue Type: Improvement
Components: WMS
Environment: ALl
Reporter: Phil Scadden
Assignee: Andrea Aime
Priority: Minor
Fix For: 2.1.x
The issues as explained by Andrea Aime.
"In GeoServer we have to reproject the filters to the native SRS before
they hit the data sources, since none of them is capable of handling
filters in a srs other than the native one.
In WFS we have good support for both parsing the srs and reprojecting the
filter back to the native store srs, but in SLD handling we don't have anything
like that.
We'd need to check if the (old) SLD 1.0 parser is able to attach the srs
information
to geometries, if so adding filter reprojection would be possible using the
same machinery used for WFS
If anybody feels like implementing this I can give directions on what code to
touch."
