The 74th Constitution Amendment Act - 1992 and more specifically under the 12th Schedule of Municipal Functions envisages among others, the preparation of spatial plans for economic development and social justice for all urban areas. Considering the same, National Urban Information System (NUIS) is approved as National Mission Programme of Ministry of Urban Development (MUD, GOI). NUIS comprises of broadly two major components - (a) Urban Spatial Information System (USIS) to meet the Spatial (maps / images) data / information requirements of urban planning and management functions, (b) National Urban Data Bank & Indicators (NUDB&I) to develop town-level urban database to support development of indices through a network of Local Urban Observatories (LUOs) under the National Urban Observatory (NUO) Programme.
Under USIS of NUIS a comprehensive 3-tier GIS database for each town/city to support the urban planning and management is envisaged:
Generate 1:10,000 scale GIS-compatible spatial information from IRS images and integrate attribute information to enhance Master Plan / Development Plan of urban settlements
Generate 1:2,000 scale GIS-compatible spatial information from aerial photographs and integrate attribute information to enhance Municipal Plan / Zonal Plan and detailed Town Planning schemes.
Establish a 1:1000 scale utilities GIS using Ground Penetrating Radar data on a pilot basis to include water-supply, sewerage, power and communication for Utilities Planning and Management.
DOS is participating in the endeavor of NUIS taken up under NNRMS Standing Committee on Urban development. Apart from providing IRS satellite data and aerial photography, DOS shares the responsibility of the preparation of thematic maps at 1:10,000 scale. In Phase-I, 158 towns covering geographical area of around 55,755 sq km has been taken up. As a pilot project, thematic mapping for the Korba town located in Chattisgarh State covering 276 sq km. has been completed. About 75 towns has been completed during 2009 and planned to complete the remaining towns in 2010.
