Category: Geographic Information Systems/Spatial Analysis // In The ESRI Guide to G/S Analysis, Volume 1, author Andy Mitchell showed how the creation and visual study of maps could be used to analyze spatial relationships between things that happen or exist in the world and their relative locations. But when the phenomena under study become complex, and the datasets huge, visual analysis alone tells only part of the story. // In The ESRI Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics, Mitchell takes us deeper, showing how an emerging set of tools that rely on spatial statistics provides GIS users the capability to conduct detailed, mathematical analysis of geographic information. // This second volume introduces statistical tools, geared specifically for geographic analysis, that are relatively new to GIS software packages and thus to most GIS users. It shows the tools in use in many different applications, explains which tools are best with which situations, and provides guidance on interpreting the results you get. // The ESRI Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics focuses on four fundamental tasks of statistical analysis: // • Calculating the center, dispersion, and trend // • Identifying patterns // • Identifying clusters // • Analyzing geographic relationships // Whether you’re new to GIS analysis or are an experienced practitioner, volume 2 of The ESRI Guide to GIS Analysis, like volume 1 before it, is a must-have.

// “A useful, user-friendly introduction to a number of spatial analytic routines. Relatively complex statistical operations are made accessible to those seeking solutions to map pattern problems. ” // Dr. Arthur Getis, San Diego State University // “One of the most well-written and easy-to-understand books for the thousands of GIS analysts often intimidated by the use of statistics and spatial analysis methods. ” // Dr. Arthur Lembo Jr., Cornell University // 97279 // DOME7.5M6/O5dm Printed in the USA // // Andy Mitchell is the author of The ESRI Guide to GIS Analysis, Volume 1: Geographic Patterns and Relationships and Zeroing In: Geographic Information // Contents // Preface... // Acknowledgments // vii // ix // CHAPTER I: INTRODUCING SPATIAL MEASUREMENTS AND STATISTICS // What are spatial measurements and statistics?... // Geographic analysis with statistics... // Understanding data distributions... // CHAPTER 2: MEASURING GEOGRAPHIC DISTRIBUTIONS // Why measure geographic distributions?... // Finding the center... // Measuring the compactness of the distribution... // Measuring orientation and direction... // References and further reading... // 21 // 22 // 26 // 39 // 45 // 61 // Testing statistical significance // 63 // CHAPTER 3: IDENTIFYING PATTERNS... // Why identify geographic patterns?... // Using statistics to identify patterns... // Measuring the pattern of feature locations . . .
