This document discusses the role of geographic information systems (GIS) in knowledge management (KM), long-range strategic planning (LRSP), and exploration. It states that GIS is strongly supported as an essential tool for capturing, analyzing, and transferring geographically-referenced data and information to enable decision-making. Current and potential future uses of GIS in exploration include play mapping, analysis, and resource assessment to support KM, LRSP, and focusing exploration strategies. Overlaying various geologic factor maps in GIS applications allows identification of key play segments.
