Information collected by public bodies often has significant economic or social worth. This data ranges from postcodes to traffic CCTV and is estimated to be worth over £100billion to the UK economy. At present, organisations like the Ordnance Survey and the Met Office fund their data collection by selling the information. This POSTnote looks at the issues of giving easy access to information along with how to maintain its quality and security. For further information please contact Dr Martin Griffiths.
