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.

Data preparation

As with almost all GIS projects, there is a considerable amount of data preparation work that must be done before the analysis can begin:

Open ArcMap with the SanAntonioRealEstate.mxd file found in your C:\GeospatialTraining\SpatialStats folder.
Remove or turn off the visibility of the BexarCountyCensusBlockGroups layer.
Add the ZillowNeighborhoods-TX shapefile. You should now have layers for ResidentialSales, ZillowNeighborhoods-TX, and a basemap layer.

The Zillow neighborhoods data doesn't include full coverage of every area within the San Antonio metropolitan area.

Obtain a count of the number of sales along with the average and sum of each numeric attribute for each neighborhood using the spatial join functionality in ArcMap. To accomplish this, right-click on the ZillowNeighborhoods-TX layer and navigate to Joins and Relates | Join.
