OS OpenSpace and Google Latitude
I’ve just knocked up a little application that brings together the Google Latitude service with the Ordnance Survey OpenSpace API.
A number of guys in the team have signed up for Latitude and enabled sharing their location. Latitude provides the ability to request a users last know location as either a JSON or KML document; in this case I’m requesting the location of the guys as a JSON feed which is then simply displayed in the user list and on the OpenSpace map.
Clicking on a user in the user list simply centres the map and displays some information about their location including a reverse geocode and accuracy.
