Hello Michael
The WKT is valid, but it conforms the ISO 19162:2019. Apache SIS
implements ISO 19162:2015; we have not yet upgraded to the 2019
revision. This is something we really want to do, hopefully this year.
But this is a task that need to be done together with an upgrade to ISO
19111:2019 and to version 10 of EPSG database.
In the meantime, the WKT in the first method of the test case you
provided can be downgraded to ISO 19162:2015 as below:
* Rename GEOGCRS as GEODCRS ("G" changed to "D").
* Rename ENSEMBLE["World Geodetic System 1984 ensemble", …] (8 lines)
by DATUM["World Geodetic System 1984"].
In theory it should be sufficient. In my test I saw that the code
complains about missing semi-major and semi-minor axis length, but it
should be possible to fix by adding the following lines together with
other parameters. I would need to check the code again, but it may be
because SIS does not know which ellipsoid to use between "Clarke 1880"
and "WGS 84".
PARAMETER["semi_major", put value here],
PARAMETER["semi_minor", put value here],
Martin
