Geospatial decision support systems: Use of criteria based spatial layers for decision support in monitoring of operations

Abstract

This paper brings out a conceptual approach for geospatial analysis for decision making process while monitoring operations. It capitulates on the ability of GDSS to support GIS layers. The decisions, decision making processes and the time involved are all broken down to a function of criteria over a set of information. This information is recommended to be stored in layers in special criteria based spatial form which reduces the processing requirements to simple manipulation of specific independent layers. This enables incremental decisions based on adequate set of data as and when required, which is akin to anytime algorithm. The human and machine analyses are integrated in a geo-visual analytical model. A case study of evacuation of an injured person from a mine using helicopter is presented. In this example all advantages of the concept are proven.
