Historical UK Maps API

National Library of Scotland Maps API

The National Library of Scotland has released an API to give developers access to a map of the UK using out of copyright Ordnance Survey maps, dating from the 1920s to the 1940s.

The API uses Google Maps to create an interactive map based on tiles created from the Ordnance Survey Maps. You can see the basic map here. This map can be embedded into other websites and blogs just by copying and pasting the iframe code. You can even embed a map using a dynamic URL so that the embedded map is zoomed and centred on your chosen location.

However you can also use the API to create your own mashups. For examplehere is a map that has an added transparency slider, that allows you to view the Google Map tiles beneath the OS maps. 

Americas Rock on Twitter

Twitter Top 100 Users

This Google Map of the Top 100 Twitter users (based on the number of followers) reveals that only 7 of them live outside of the Americas. Those 7, who are all based in Europe, even include Brazilian footballer Kaka and U.S. tennis player Serena Williams.

The markers on the map are colour-coded by category, for example, music, entertainment, technology etc. Like BatchGeo's Map of Top 100 Websites Worldwide the map features a really cool marker clustering system. Not only does each clustered marker show the number of markers at the location it features a nice pie chart that represents the percentage of each website category at the location.
