Geographical information system or GIS is a system design to capture, store, manipulate, analyze, manage and present spatial or geographical data. It is attached to many operations related to Biology. GIS and location intelligence applications can be the foundation for many location enableed services that rely on analysis and visualisation. Therefore, the aim of this study is to know about the distribution of water bodies containing Nymphaea alba within the kharagpur subdivision of paschim Medinipur district of West Bengal using Geospatial Technology. Nymphaea alba is a floating fresh water plant with floating leaves. Those plant helps to purify West water by absorbing inorganic nutrients through their rhizomes. Software programs like Google earth and web features like Microsoft visual Earth are changing the way of geospatial data is viewed and shared in this investigation. The distribution of GP under kharagpur subdivision, drawing done by using contemporary survey methods. Location of this place is 21°76` N- 22°56` N and 87°12` E- 87°72` E. It's covers an area of 2913.17km* and compromise of 10 community development blocks, 10 panchayat samiti, 99gram panchayat ( GP),2679 mouse's and 2486 inhabited villages. Total 1767 water bodies present in this area which are fresh water type. Among them 1520 water bodies shows the sources of Nymphaea alba. This type of investigation will be help full to local farmers as well as Government policy makers as they can use the sources of food and bio control for water pollution.
