I see now what the problem was: the Z coordinate is indeed populated,
but it is not outputted by WTKWriter. Which is a problem for WFS.

The JTS WKTReader does respect Z ordinates in WKT, and will populate
the Z field in the Coordinate objects created. This works for all
geometries.
However, the WKTReader does not (yet) handle the new(ish) POINT Z
(...) syntax (or the M syntax, for that matter).

Hi Niels,
COrrect, there are not many tests if any that test 3d/2.5d data
through the pipeline. Martin did a bunch of stuff recently to
start testing this and soon tests should start showing up in
GeoServer. We also discussed what support for 2.5d data we get
with property datastore.
As far as I know the JTS WKT reader will respect a third
coordinate. For instance if i parse POINT(1 2 3) I do get back a
Point that has an underlying coordinate that maintains a z value
of 3. Not sure about the other geometries but the impression I got
from Martin is that its maintained. Writing I believe might be a
different story.
Long story short through I believe you can use property datastore
as it is today to test 2.5d as long as you are not doing transactions.

Hi,
I am trying to write some unit tests in geoserver that use 3d
geometries, and was looking for examples but cannot actually
find much
3d geometry testing on the geoserver side.
I tried using property files with WKT, however the WKT format
for 3d
geometries doesn't seem to be supported, for example a 3d
point would be
encoded as
Point Z (x y z)
Am I correct to say this is not supported yet? I want to
implement this
for property files. Anyone have any experience in how to do
something
like that?
Cheers
Niels
