Written for petroleum professionals, this book uses non-technical language to describe Geographic Information Systems (GIS), their core features, and the benefits associated with their use. Gaddy (an operations manager) specifically discusses topics like spatial models and spatial analysis, cartography, remote sensing, GPS, data quality, interpretation, and presentation. Case studies relate upstream, midstream, and downstream experiences. Numerous maps, photographs, and diagrams (including many in color) support the discussion.
