[Geoserver-users] WFS-T with compound CRS (EPSG:7415)

Sjoerd_Brandsma · July 20, 2011, 8:05am

Hi all,

Should it be possible to use WFS-T with a compound CRS like EPSG:7415 (Projected + Vertical)
We made some local patches to get our in-house developed flash application working with WFS,
postgis DB and GML 3.1.

For WFS-T we run into some ‘conversion to MathTransform2D’ problems.

I assume this also needs some code changes?

Best regards,

It likely does, transformations from plain to compound srs do not work as of now

Can you give me any hints where to start to implement/patch geoserver so it can handle
compound crs coordinates with WFS-T?

thanks,
Sjoerd

A lot of the referencing stuff shows up in the GeoTools math (i.e. in the gt-referencing module).

Ah, besides Jody's suggestion, which is sort of the "high path",
better but harder,
the WFS code could be modified to extract the horizontal part of a compound
reference system using the CRS utility class.
It all boils down to where in particular that error happens. If it's
just to report
the modified area to the transaction listeners/plugins getting the horizonal
portion of the CRS might well work fine
