We have been doing some work with AJAX methods provided by the OS Openspace API. To help anyone else out there working on this we have provided a simple example that loads a list of coordinates and URLs from a text file and uses these to add markers to a base map. In this example the marker, when clicked, reveals a live “sky cam” image, usually provided by a personal weather station website.
The application is created using the Ordnance Survey OpenSpace API including their loadurl AJAX method. Zoom in on the map and you’ll see it’s a real OS map! We also have a version using Google Maps.
