Datastream.observedArea for a single point #9

Open hylkevds opened 8 years ago

hylkevds commented 8 years ago

Hi All,

Datastream.observedArea is defined as GM_Envelope (GeoJSON Polygon) What to do when the features of interest for a given Datastream are just a single point?

  1. Return a Point (though the standard states it should be a polygon)?
  2. Return a polygon containing just 4x that point as corners?
  3. Return nothing?

What's the general opinion on this?

Anyone knows how does typical OGC capabilities XML handle this?

+1 on this issue as it somewhat relates to the issues in #33

We could change the definition for v1.1 to allow non-polygons (any GeoJSON object) for the Datastream.observedArea. Or would there be issues with that?
