Summary: Supports GGXF for datum shifts and geoidal heights
Key: SIS-534
URL: https://issues.apache.org/jira/browse/SIS-534
Project: Spatial Information Systems
Issue Type: New Feature
Components: Referencing
Reporter: Martin Desruisseaux
The [Gridded Geodetic data eXchange
Format|https://github.com/opengeospatial/CRS-Gridded-Geodetic-data-eXchange-Format]
(GGXF) is an OGC standardization effort for distributing datum shift grids (in
replacement of e.g. NADCON and NTv2), geoid models, and more geodetic gridded
data. A draft of the standard and a prototype in Python are available. We
should support this format in Apache SIS, integrate it within the
{{sis-referencing}} module and test with datum shifts.
