The amount of data generated in this digital era is phenomenal, wherein the decision maker has to depend on hierarchy for relevant information, which results in delay due to lack of timely data verification. Contemporary decision-making thus becomes complex. In view of this an attempt has been made to design and develop a Decision Support System – DRIS
For efficient administration, whether it is at micro-level or at macro-level, planning is an accepted way to handle complex problems of resource allocation and decision making. It involves the use of collective intelligence and foresight to chart direction, order, harmony and progress in public activity relating to human environment and general welfare.
The amount of data generated in this digital era is phenomenal, wherein the decision maker has to depend on hierarchy for relevant information, which results in delay as well as inaccuracies due to lack of timely data verification. Contemporary decision-making thus becomes complex and involves a wide spectrum of knowledge sourced from diverse fields. For dispensing their needs and to facilitate transparent and rational planning, it is pertinent to have a decision support system, which is cost effective and user friendly. GIS has a unique capability in database storage and analysis, which in turn make the decision support task flexible.
In view of this an attempt has been made to design and develop a Decision Support System ” DRIS” (District Resource Information System) using Arc GIS. DRIS is a customized software, developed using Avenue scripts under ArcView environment, to organize the GIS database and decision support functions into a unified form, which can display various geo-spatial layer and can accept non spatial data sets. It can also generate maps based on various queries, so that the user can efficiently perform decision support tasks. It can also display tabular data along with the theme.
Village level socio-economic information such as demographic data, amenities and infrastructures etc., can be available at a few clicks. Mathematical and logical queries based on various attributes can be carried out. Complete information about any village can also be obtained by just clicking the menu and buttons. Automated block ranking on the basis of socio economic constraints can be obtained by clicking the menu. The map composition of various outputs can be generated. Database can be updated. Testability and validity of the proposed DRIS software package has been carried out by implementing it as decision support tool for the district Hoogly (Lat: 22° 32’ to 23° 15’ E and Long: 87° 30’ to 88° 32’ N) of West Bengal, India.
