example POI output from OGC API Features server

[geofizzydrink]

This issue is intended to be the initial space for discussion of examples of POI output from OGC API Features servers.

Initially the examples here will describe the JSON output that will eventually come automatically from the TerraNexus ogcapi server (which implements a number of OGC API's including the Features API).

Once we're happy with this it will then make sense to include this/these examples in the Best Practice Guide Document.

Initial JSON example - GeoJSON (no "hasPayload" property) - representing the POI as a point object that references the full polygon Feature (would this break anything in terms of the Feature Model???)

Consider an example of a building with three levels of abstraction:

• Level 0 - the building location as a point POI
• Level 1 - the building footprint as a polygon POI
• Level 2 - the full building model as CityGML
