Overview of this book

Data scientists, when presented with a myriad of data, can often lose sight of how to present geospatial analyses in a meaningful way so that it makes sense to everyone. Using Python to visualize data helps stakeholders in less technical roles to understand the problem and seek solutions. The goal of this book is to help data scientists and GIS professionals learn and implement geospatial data science workflows using Python. Throughout this book, you’ll uncover numerous geospatial Python libraries with which you can develop end-to-end spatial data science workflows. You’ll learn how to read, process, and manipulate spatial data effectively. With data in hand, you’ll move on to crafting spatial data visualizations to better understand and tell the story of your data through static and dynamic mapping applications. As you progress through the book, you’ll find yourself developing geospatial AI and ML models focused on clustering, regression, and optimization. The use cases can be leveraged as building blocks for more advanced work in a variety of industries. By the end of the book, you’ll be able to tackle random data, find meaningful correlations, and make geospatial data models.

Summary

In this chapter, you learned how to construct multiple hypothesis tests. Each hypothesis test was conducted with the null hypothesis (H0) as CSR. The alternative hypothesis (Ha) in each case was that data exhibited a non-random, spatially significant relationship.

For data where the attribute features were important, you conducted tests of global spatial autocorrelation, leveraging Moran’s I and Geary’s C. You also learned how to identify known spatial outliers and hot and cold spots through the use of LISAs.

At the end of the chapter, you learned how to conduct hypothesis testing on point data where the distribution of the points themselves was of interest. The tests you conducted here were based on Ripley’s alphabet functions, which looked at the nearest neighbor distance distributions and full-distance distributions.

Now that you’ve thoroughly explored this data, it can be leveraged in future exercises. We hope you’re excited to...
