Milton Keynes collaborated with European Space Imaging partner Satellite Applications Catapult, to investigate whether a more effective method could be found to detect changes to land over time, ensuring that planning management policies were adhered to. Milton Keynes is one of the fastest growing cities in the UK and a great economic success story. However, the challenge of supporting sustainable growth without exceeding the capacity of the infrastructure, and whilst meeting key carbon reduction targets, is a major one. In 2013, Milton Keynes collaborated with European Space Imaging partner Satellite Applications Catapult, to investigate whether a more effective method could be found to detect changes to land over time, ensuring that planning management policies were adhered too. The result is a smart city innovative planning application tool known as Keyne Eye and is due to be completed later this year (2017).
