UK Ordnance Survey OpenSpace Map With Markers Loaded From A File

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 Fixed and Cluster strategies.  The former on loading reads static data once from a file.  The latter modifies the number of markers shown according to the detail available at different zooms.
