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 continued to learn about SQL queries as a way to filter datasets and generate focused responses to questions. The goal for writing SQL syntax is to feel conversational—building on the ability to ask specific questions. Understanding location and being able to dig a little deeper to see how “where” things are happening can often shed insight on “why” as well.

Writing conditional and aggregation data queries integrated nicely into specific workflows that you can expand as we dig deeper into the platforms that host the SQL consoles and windows.

In the next chapter, we will dig a little deeper into PostgreSQL by exploring pgAdmin in more detail and how to integrate PostGIS with QGIS.
