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.

Creating Hot Spot maps from point data using the Optimized Hot Spot Analysis tool

The Hot Spot Analysis and Optimized Hot Spot Analysis tools are traditionally used with polygon data. However, there may be times when your source data is represented by point locations. These locations may or may not have applicable attribute information.

There are two ways to handle this situation. If you have a suitable boundary layer such as census tracts or blocks, ZIP codes, or other political boundaries, you can aggregate the point data to the boundaries and then perform the hot spot analysis. You've already seen some examples of this. But there may be times when you don't have a suitable boundary layer to aggregate the points or simply want to use the point layer instead. In these situations, you can use the Optimized Hot Spot Analysis tool to create a fishnet of rectangular features to use as the aggregation layer. In this exercise, you'll learn how to use this tool with point features to generate a...
