Sorry Ian,
I don't get it. I create a Coordinate and pass 3 values:
enh.getX(),enh.getY(), enh.getZ(). Why are you telling me I pass 2? I
also stated I check in the debugger the Coordinate has x, y, and z.

Hi Ian
My points have a dimension of 3, see below, or let me repeat here:
gf.createPoint(new Coordinate(enh.getX(), enh.getY(), enh.getZ()
My points have X,Y,Z. The problem is that the CRS returns 2 as
dimension, which is correct
No that is the problem - your points have a dimension of 3 so you
should not pass in 2 here. You could try calling
`org.geotools.geometry.jts.LiteCoordinateSequence.guessDimension(Coordinate...)`
which should return 3 for your data.
, but in PackedCoordinateSequence it does this check (dimension -
measures < 2) and this measures is 1. measures comes from my Point
which contains XYZ (I checked in the debugger) when it gets
converted to CoordinateSequence and this CoordinateSequence
returns the 1 for the measures (cs.getMeasures()).
I have no clue what that measures meansand why it is 1. I also do
not understand why it is necessary to involve a CRS to get a
dimension if a Point gets (just) cloned.
measures are the M of a POINTMZ or POINTM (so yet another dimension to
the coordinate) - you should get 3-1 = 2 (x,y) and all should be well.
Yes, it is a show stopper. What I want to try is, use jts-1.11
instead of jts-1.18. Not sure if that is compatible with Geotools
25.2. It is also not clear to me, who is responsible for jts. Is
it the Geotools team, or some other team.
It looks like it is a geotools problem, so as a first step raise an
issue (https://osgeo-org.atlassian.net/jira/software/c/projects/GEOT
<https://osgeo-org.atlassian.net/jira/software/c/projects/GEOT>)
preferably with a test case. Then either wait for a fix to come, or
implement a fix or incentivise someone to care about it for you.
