UK Ordnance Survey OpenSpace Map With Markers Loaded From A Server

Created Using UK Ordnance Survey OpenSpace API

Demonstrates reading markers (features) as GeoJSON, and other formats by analogy, using the HTTP Protocol, and also the client side of the BBOX and Cluster strategies.  The former makes multiple parameterised reads (from an appropriate BBox-capable geo-server here emulated inappropriately, but simply, by a file) of just sufficient data to keep the viewport populated as the map is panned about.  The latter modifies the number of markers shown according to the detail available at different zooms.
