But I agree that we should correctly extend the default bounding box of Europe in the EGDI metadata catalogue to include Greenland. We will add it to the development.

EPSG:3034 which is the default display projection of the portal (see #346) has a bounding box of BBOX[24.60,-35.58,84.17,44.83], however that doesn't cover Greenland.

Extents for Greenland (EPSG:1107) are

<gmd:EX_GeographicBoundingBox>
    <gmd:westBoundLongitude>
      <gco:Decimal>-75</gco:Decimal>
    </gmd:westBoundLongitude>
    <gmd:eastBoundLongitude>
      <gco:Decimal>8.12</gco:Decimal>
    </gmd:eastBoundLongitude>
    <gmd:southBoundLatitude>
      <gco:Decimal>56.38</gco:Decimal>
    </gmd:southBoundLatitude>
    <gmd:northBoundLatitude>
      <gco:Decimal>87.03</gco:Decimal>
    </gmd:northBoundLatitude>
</gmd:EX_GeographicBoundingBox>

Which would give a Europe bounding box of:

<gmd:EX_GeographicBoundingBox>
    <gmd:westBoundLongitude>
      <gco:Decimal>-75</gco:Decimal>
    </gmd:westBoundLongitude>
    <gmd:eastBoundLongitude>
      <gco:Decimal>44.83</gco:Decimal>
    </gmd:eastBoundLongitude>
    <gmd:southBoundLatitude>
      <gco:Decimal>24.6</gco:Decimal>
    </gmd:southBoundLatitude>
    <gmd:northBoundLatitude>
      <gco:Decimal>87.03</gco:Decimal>
    </gmd:northBoundLatitude>
</gmd:EX_GeographicBoundingBox>

I'm not sure though of the merit of having a metadata bounding box for a set of data (a hint to the location) that is much different to the actual extent.

In the prototype map for FRAME in EGDI you can see well Greenland. Here is the link https://data.geus.dk/egdi/?mapname=egdi_geoera_frame#baslay=baseMapGEUS&extent=-11549890,-3443450,19362370,10587820&layers=frame_metallogenic_areas,frame_mineralisation_points
That's why I'm not sure if I understand your last sentence...

What I meant was you should use the extent of the actual data in the metadata.

In the prototype map for FRAME in EGDI. The two layers have auto-generated ISO metadata (created by MapServer)

REE mineral occurrences (prototype) has
https://egdi.geology.cz/record/xml/5efb2a53-29d0-458a-9eee-0bfa0a010833

with

<gmd:EX_GeographicBoundingBox>
    <gmd:westBoundLongitude>
        <gco:Decimal>-60.00</gco:Decimal>
    </gmd:westBoundLongitude>
    <gmd:eastBoundLongitude>
        <gco:Decimal>35</gco:Decimal>
    </gmd:eastBoundLongitude>
    <gmd:southBoundLatitude>
        <gco:Decimal>27.5</gco:Decimal>
    </gmd:southBoundLatitude>
    <gmd:northBoundLatitude>
        <gco:Decimal>83.50</gco:Decimal>
    </gmd:northBoundLatitude>
</gmd:EX_GeographicBoundingBox>

and

REE metallogenic map of Europe (prototype) has
https://egdi.geology.cz/record/xml/5ef9b687-7464-48d1-a170-548a0a010833

with

<gmd:EX_GeographicBoundingBox>
    <gmd:westBoundLongitude>
        <gco:Decimal>-60.00</gco:Decimal>
    </gmd:westBoundLongitude>
    <gmd:eastBoundLongitude>
        <gco:Decimal>35</gco:Decimal>
    </gmd:eastBoundLongitude>
    <gmd:southBoundLatitude>
        <gco:Decimal>27.5</gco:Decimal>
    </gmd:southBoundLatitude>
    <gmd:northBoundLatitude>
        <gco:Decimal>83.50</gco:Decimal>
    </gmd:northBoundLatitude>
</gmd:EX_GeographicBoundingBox>

So I would suggest using that extent

@Kramolisova can this now be closed?

We decided within metadata team to not extend predefined spatial extent of Europe in MIcKA with Greenland yet.
