Two important initiatives are converging at this time: Open Government and Smart Cities. The goal of Open Government is to make government more open and democratic by providing citizens and corporations access to information about their cities and how they operate. Consequently, cities around the world are pursuing an “Open Data” policy. The goal of Smart Cities is to identify ways in which scarce resources can be more effectively deployed to meet the needs of its constituents. Both rely on the ability to represent and reason about city data. Accordingly, the purpose of the Smart Cities Mission is to drive economic growth and improve the quality of life of people by enabling local area development and harnessing technology, especially technology that leads to Smart outcomes. Area-based development will transform existing areas (retrofit and redevelop), including slums, into better planned ones, thereby improving liveability of the whole City. Application of Smart Solutions will enable cities to use technology, information and data to improve infrastructure and services.
