Spatial Database Management System for Standing Water Resources using Relational Properties

摘要

This research aims to apply an integrated approach of geographic information system (GIS) and relational properties of database to develop a database information system for standing water bodies from extracting required data from digitized maps whichis in the form of spatial data in eastern region of country viz. Bihar, Jharkhand and West Bengal. A number of spatial data bases and digitized maps are available related to water resources. But these spatial data do not easily define the available standing water bodies in Bihar, Jharkhand and West Bengal. So it is a challenge to extract required non spatial data in easily understandable form and recreate the spatial data as required by the user. An analysis has been done on available spatial data and maps to get non spatial/ tabular data which are in more easily understandable form. Data extracted district-wise related to area and number of standing water bodies according to their size of Bihar state. Various spatial data, maps, geodatabases have beencollected from different organisations and institutes. After that an analysis using some data mining techniques has been done to get non spatial/ tabular data in easily understandable form and some required digitized maps have also been created using GIS technique as required. This type of information is more useful than the spatial data because a common person is able to understand these tabular data and they can use these data for their own purposes. These data can be utilised by a scientific personnel as well as farmers of these area and that will be used in agriculture for better utilization of water resources to enhance agricultural productivity and income of farmers of these states.
