UK: Ahead of the local and European elections last month, and the recent Newark by election, Ordnance Survey has replaced its previous election maps website with an updated map.
The election maps website lets users overlay the official boundaries of constituencies and wards on Ordnance Survey maps at various scales. This is particularly useful at street level, where canvassers working for local candidates need to know which side of the street to cover; or how far along the street to go.
OS has stated that much of the new election maps website has been built using some of its freely available OS OpenData products, including Boundary-Line. A host of improvements include a bigger map window, easier navigation, slicker searching and more.
