Applicable 2D CRS for Domain

[KathiSchleidt]

INSPIRE requires the use of the Zoned Geographic Grid from the Geographical Grid Systems Theme, defined in IR Requirement - Annex III Section 1.7.2 - Geographic Grids. This stipulates the use of any grid compatible with one of the following coordinate reference systems may be used for making gridded Elevation data available:
– two-dimensional geodetic coordinates (latitude and longitude) based on a datum specified in Section 1.2 of Annex II and using the parameters of the GRS80 ellipsoid;
– plane coordinates using the ETRS89 Lambert Conformal Conic coordinate reference system;
– plane coordinates using the ETRS89 Transverse Mercator coordinate reference system.

Based on this, when utilizing geodetic coordinates, we can use EPSG::4258 for the horizontal component of the Coverage.

No determination has been made towards plane coordinates, as not directly relevant to the RWS PoC, but would be valuable.

Update on updating INSPIRE CRS, according to INSPIRE-MIF Helpdesk Issue 33 Amendment to IR 1089/2010 to allow for a CRS registry to be established is expected for the 2nd Quarter of 2022, will allow for extending the list of allowed CRS.
