Hi Olle, Andrea,
I was looking at the Microsoft JDBC driver docs this weekend and noticed
that the MS driver now actually has both a Geometry and a Geography
class now that provide both a STGeomFromText(String wkt, int SRID) and a
STGeomFromWKB(byte[] wkb) method [1] as well as STAsBinary()/STAsText()
methods so going back-and-forth to eg a JTS geometry should be a breeze.
It may be worth considering a new module or dialect that leverages the
possibilities that the JDBC driver exposes instead of continuing on the
old path of decoding shapes, segments and figures from the binary data
which gets increasingly difficult with compound objects.
This may mean dropping support for sqlserver 2014 and definitely the
jdts driver, het good thing is that the Microsoft driver is now
available in Maven Central[2] and available as Open Source[3] (MIT
licensed) so no hassle with separate downloads and installs.

Hehe yeah I understand :)
I’ll try to make the estimate myself.

Hi Olle,
I have them, but we don't discuss estimates outside of private
business inquiries, sorry :-)
That said, estimates are personal, they change depending on
experience, topic and the like, so
they would not be much use anyways.
If you decide you want someone else to do it for you, you can
contact commercial support providers
to get an estimate:

Cheers

Hi Andrea and Mark
Thank you for the swift response!
Andrea, do you have a ballpark number of hours it took to
implement the support for curves in Oracle or PostGIS?
Mark, did you have an estimation to complete the work you started?
If I don’t find the time myself I’ll try to find funding and
seek commercial help and then it would be great to have a
ballpark number to start with.
Regards,
Olle Markljung

Ik had a look into this some years ago but our funding
evaporated, so it
stranded, see https://osgeo-org.atlassian.net/browse/GEOT-5512
some unfinished work is in:
https://github.com/mprins/geotools/commit/e43286e7bae7101af0dad4edbee40f99ca81d4eb
