Waag was present with the Smart CitySDK project at the OpenStreetMap conference State of the Map this year. This event was held from 6-8 September 2013 in Birmingham, UK. Bert Spaan, known as the developer of the map of all buildings in the Netherlands, spoke at the conference.
We made a poster for the occasion that clearly shows how the OpenStreetMap is used as a base layer within CitySDK API and is enriched by the open data from the participating cities. The CitySDK API functions as a distribution platform for linked open data.
The poster can be downloaded for free. CitySDK is the easiest way for cities to make their data accessible and publish them as '5-star linked open data'.
