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.

Many things in life naturally tend to cluster. Housing, businesses, trees, and crimes are all examples of clustering. The degree of this clustering is important. The tools in the Mapping Clusters toolset don't just answer the question "Is there clustering?", but they also answer the question "Where is the clustering?"

The Mapping Clusters tools are helpful in identifying statistically significant hot and cold spots, spatial outliers, as well as locating similar features, and grouping features. This toolset can also be used to define actions that should take place based on the location of clusters. For example, the Mapping Clusters tools can be used to identify areas of high crime activity (burglaries, for example) that can be useful in allocating police officers to deal with this activity in those areas. While these clusters don't typically identify why a phenomena is occurring, they can often provide clues.

The tools in this toolset allow us to...
