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 Multi-Distance Spatial Cluster Analysis tool to determine clustering or dispersion

Multi-Distance Spatial Cluster Analysis (Ripleys K Function) determines whether feature locations show significant clustering or dispersion. However, unlike the other spatial pattern tools that we've examined in this section, it does not take the value at a location into account. It only determines clustering by the location of the features. This tool is often used in fields like environmental studies, health care, and crime, where you are attempting to determine if one feature attracts another feature. Also, keep in mind that a dataset can be both clustered and dispersed as seen in the line graph on this slide. We'll examine what this means in more detail on the next slide.

In this exercise, you'll use the Multi-Distance Spatial Cluster Analysis tool to analyze the clustering or dispersion of burglaries.



Let's get prepared by performing the following steps to learn to use the Multi-Distance...
