The third volume in the Esri Guide to GIS Analysis series, Modeling Suitability, Movement, and Interaction describes practical applications of modeling concepts in a geographic information system (GIS). Modeling allows users to explore different scenarios and the impacts of various options, before making a decision. This book covers a broad range of methods for spatial interaction, site selection, routing, and scheduling, and explains the theory behind them so users can better interpret the analysis results. It also describes how a particular method is implemented within a GIS. With full-color maps and illustrations and sample applications, this book will help students studying GIS and professional GIS analysts better use models to evaluate locations and analyze movement.
