Spatial Analytics with ArcGIS

By: Eric Pimpler

Overview of this book

Spatial statistics has the potential to provide insight that is not otherwise available through traditional GIS tools. This book is designed to introduce you to the use of spatial statistics so you can solve complex geographic analysis. The book begins by introducing you to the many spatial statistics tools available in ArcGIS. You will learn how to analyze patterns, map clusters, and model spatial relationships with these tools. Further on, you will explore how to extend the spatial statistics tools currently available in ArcGIS, and use the R programming language to create custom tools in ArcGIS through the ArcGIS Bridge using real-world examples. At the end of the book, you will be presented with two exciting case studies where you will be able to practically apply all your learning to analyze and gain insights into real estate data.

Using the Grouping Analysis tool

The Grouping Analysis tool groups features based on feature attributes as well as optional spatial/temporal constraints. The output of this tool is the creation of distinct groups of data where the features that are part of the group are as similar as possible and between groups are as dissimilar as possible. The tool is capable of multivariate analysis and the output is a map and a report. The output map can have either contiguous groups or non-contiguous groups. With contiguous groups, there is an added spatial component that can limit the effectiveness of the results. The creation of sales territories would be an example of a contiguous group. When groups are created in a non-contiguous manner, we allow the data to speak for itself without the introduction of a spatial limiter.

The output from the Grouping Analysis tool consists of a map along with a box plot, as shown in the following screenshot. By itself, the map doesn't tell you a whole lot. Obviously...
