Geospatial Analysis with SQL

By: Bonny P McClain

Overview of this book

Geospatial analysis is industry agnostic and a powerful tool for answering location questions. Combined with the power of SQL, developers and analysts worldwide rely on database integration to solve real-world spatial problems. This book introduces skills to help you detect and quantify patterns in datasets through data exploration, visualization, data engineering, and the application of analysis and spatial techniques. You will begin by exploring the fundamentals of geospatial analysis where you’ll learn about the importance of geospatial analysis and how location information enhances data exploration. Walter Tobler’s second law of geography states, “the phenomenon external to a geographic area of interest affects what goes on inside.” This quote will be the framework of the geospatial questions we will explore. You’ll then observe the framework of geospatial analysis using SQL while learning to create spatial databases and SQL queries and functions. By the end of this book, you will have an expanded toolbox of analytic skills such as PostGIS and QGIS to explore data questions and analysis of spatial information.

In this chapter, we dove a little deeper into a few of the tools. You learned how to load a large dataset into QGIS for access within the pgAdmin graphical interface. For me, I think it’s a good way to enhance the utility but also the limitations of using pgAdmin as a management tool. I typically use it to explore recently uploaded data via QGIS once I refresh and make sure the data tables are accessible in pgAdmin. Functions can also be run in the query editor and saved to a file to be uploaded into QGIS or your GIS of preference.

We will return to QGIS in the next chapter. Thanks for coming along.
