TREE and the Tiles terms

pietercolpaert commented 5 years ago

The Tree ontology should be able to describe a special tree: the geospatial quad-tree commonly used for maps.

See in use at https://openplanner.team/specs/2018-11-routable-tiles.html

@ddvlanck also has a use case however where the tiles need to be explicitly mentioned.

I suggest to then use something like this:

<dataset> hydra:member <>,<>, ... ;
                 tree:view <url> .

<url> tree:relation [
           a tree:GeospatiallyContainsRelation ;
           tree:value "WKTSTRING";
           tree:node <node1>
      ]; [
           a tree:GeospatiallyContainsRelation ;
           tree:value "WKTSTRING";
           tree:node <node2>
      ]; [
           a tree:GeospatiallyContainsRelation ;
           tree:value "WKTSTRING";
           tree:node <node3>
      ].

As @hdelva suggested, could other geometries for spheres also be supported? Is there existing work on that?
