Hi all.

I’m experimenting with calling WFS services with custom filtering expressions, including spatial filtering.

According to the filtering documentation, spatial filtering is possible with GML, but it doesn’t seem to work in FME ?

The geometry column is present but has no value in the output from FeatureReader, and FeatureReader has its own spatial filtering parameter separate from the “normal” filtering parameter (using <Filter/>)

Am I correct in assuming, that FME effectively prohibits any spatial filtering via the “normal” filtering parameter, and requires you to always use the special FeatureReader spatial filtering parameter ?

And maybe this is neccesitated because FeatureReader removes the WFS geometry column values ?

Thanks for any insights.

There is a known issue that affects WFS filtering, could possibly be related?

Thanks, but alas, this is WFS 2.0.0. And “WFS 3.0” is really OGC API Features, so that’s a different ball game altogether..

I was just checking any known limitations, as I off course can do all the filtering in FME itself.

I believe this at least used to work. Have you checked this?
