Abstract

The spatial decision-making process in multi-user environment is a quite challenging and complex task in group decision-making environment. The effective database design and GIS analysis techniques are very important at the host organization level. The biodiversity conservation prioritization is one of the complex issues for the conservation authorities. Various ecological and socio-economic drivers govern the spatial distribution of biologically rich communities. These drivers are important inputs to the modelling process with different rank criteria and probabilistic weight in order to arrive at a decision-making process. In the present article, a new database design and decision analysis technique is proposed for the natural resource management and planning in Web geographic information systems environment. The study is demonstrated for the geospatial decision analysis with an output validation utility where the analytic hierarchy process is used to derive the eigen vectors with given multiple constraints and conflicting criteria and aims at selecting an optimal site for the biodiversity conservations.
