in repository https://gitbox.apache.org/repos/asf/sis.git
commit e4fc9a54a7cf2ebfb3110b5163dd38a607b1568c
Author: Martin Desruisseaux <martin.desruisse...@geomatys.com>
AuthorDate: Sun Apr 23 19:02:08 2023 +0200
Make `CoverageCombiner` more suitable to public API:
- infer `xdim` and `ydim` automatically.
- check units of measurement.
