example POI output from OGC API Features server #153

Open geofizzydrink opened 3 weeks ago

geofizzydrink commented 3 weeks ago

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.
