A GPS and GIS based model for an Empirical Study of Village Information System

A study was conducted to prepare a detailed development plan based upon extensive primary survey of the village and its environment by using the techniques of GPS, GIS and managed with the database management programming language. In this study the Village Potheri, is identified as a study area with an aerial extent of 2.86 km2 in Kancheepuram District, Tamil Nadu, India. Hand-held GPS instruments (1 m level accuracy), the x,y coordinates of points (longitude and latitude) features like houses, water taps, tube wells, street lights and linear features of roads and streets has been collected and converted into shape files and accessed in GIS. The basic essential requirements of land use / land cover (classified from LISS IV), soil, geology, geomorphology and etc., were also prepared thematic maps and non-spatial information also attached with respective thematic layers. The spatial and nonspatial data were connected with VB 6.0 platform (GIS database is considering as a back end and the VB is acted as front end tool) for managing and controlling the data within GIS platform. Through this platform an attempt has been made to generate a GPS and GIS based information model for adding/inserting, deleting and retrieving data from GIS database. For retrieving data different types of queries have been developed viz., query in terms of house number, person‘s name, street wise information and thematic map wise information with non-spatial data
