[postgis-users] ST_Transform Z heights between ODN and WSG [solved]

[James Howe]

Thanks for the help to look in the right direction.
I downloaded the missing data files and it works now.

# projsync --system-directory --source-id uk_os

postgres=# SELECT st_asewkt(ST_Transform('SRID=7405;POINT(545068 258591 8.51)'::geometry, 4979));
                                st_asewkt
-------------------------------------------------------------------------
 SRID=4979;POINT(0.121584703519227 52.20646902224667 54.461915505876696)
(1 row)

I guess 3.0 reduced what was included by default?
