It helps in regular updation of database over the years to ensure better availability of Mandal information. The main objective of the study is to develop a Mandal information system providing complete information for decision-making based on their existing resources and capabilities. Hence, an attempt has been made to assess the standard of each infrastructure facility in Addanki mandal, Prakasham district. For this purpose, type of housing, roads, water supply and sanitation, electricity, telephone, transportation facilities have been identified as the major fields of the basic infrastructure. Detailed information about the infrastructure in Addanki mandal has been used for the development of the information system in ARCGIS environment. High-resolution satellite data from IRS-P6, LISS-IV –MX Resolution of 5.8m satellite has been used for the preparation of large scale base, drainage, transportation and land use/land Cover maps (1:10,000 Scale) supported with extensive field survey KEYWORDS Planning, Mandal information system, Remote Sensing, GIS. 1. INTRODUCTION within which development schemes can be planned Planners and decision-makers at Micro level have to and assessed and acceptable designs implemented. depend upon spatial and non-spatial data for optimal Mandal level information system would allow interpretation. Hence, the planners need to have at planners and citizens to quickly and efficiently create their disposal sophisticated data management systems and test alternative development scenarios and to handle such spatially correlated data. Mandal level determine their likely impacts on future land use studies are one of the most efficient ways to patterns vis-à-vis ever-increasing population allowing understand the farming systems in rural areas and public officials to make more informed planning also help in identifying the socio-economic and decisions. In short, use of (MLI) in local government institutional constraints faced by the farming administration would increase efficacy, save time, community. The emergence of Remote Sensing and improve accuracy, generate revenue, automate tasks, Geographic Information System as a powerful tool provide better decision support as well as being for spatial analysis and storage has in effect economical. alleviated the problem by computerization of the 3. STUDY AREA spatial data. This new technology can reduce the time The study area selected for the project is Addanki and cost to the planners in organizing the data in mandal, Prakasam District of Andhra Pradesh in arriving at precise conclusion and decisions. India. Prakasham is an administrative district in the Mandal Leval Information System, generated in the state of Andhra Pradesh with the district headquarters present project which integrates the spatial village located at Ongole. There are a total of 56 mandals in maps with non-spatial or tabular information, has this district occupying an area of 17,626 km² with a demonstrated its potential for grass-root level population of 3,054,941 (as of 2001census). Some of development planning taking into consideration the the main towns in Prakasam district are Markapur, local needs and constraints. Chirala, Addanki, Kandukur, Giddalur, Podili, 2. IMPORTANCE OF MANDAL Dornala, Cumbum, Kanigiri and Chimakurthi. INFORMATION SYSTEM Prakasam district occupies an area of 17626Km 2 with Mandal Information has been defined as the “process various agricultural, mining and quarrying, of recording and dissemination information about the manufacturing and other household villages resources information, census, utilities, land industries.However, The study area Addanki mandal use and use of land its associated resources”. A good is located at Longitude of 79 0 53’34.57’’ to 80 0. 2’ administration system should permit the integration 29.70’’ and Latitude of 15 0 55’38.85’’ to 15 0 41’ of village information and land use with sociological, 10.18’’. Area of Addanki mandal is 160.99 sq.kms economic and environmental data in support of (approximately) .it has a total population of 74,904 as physical planning. The availability of up-to-date per 2001 census, The mandal decadal growth rate is large-scale spatial data provides the basic framework 9.65 in between 1991-2001.
