Geographic location on metadata #391

Closed auretepereira closed 3 years ago

auretepereira commented 3 years ago

@Kramolisova Could you please provide the longitude and latitude for datasets with spatial extent in Europe (including Greenland)? Of course I can put the values but if you provide them than all should use the same values.

Thank you in advance. Best regards

EPSG:3034 which is the default display projection of the portal (see https://github.com/GeoEra-GIP/Project-Support-WP8/issues/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...

nmtoken commented 3 years ago

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

auretepereira commented 3 years ago

Ok. Thanks.

Kramolisova commented 3 years ago

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.

nmtoken commented 3 years ago

@Kramolisova can this now be closed?

Kramolisova commented 3 years ago

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