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.

Preface

This book is for learners interested in using SQL and open source platforms for detecting and quantifying patterns in datasets through data exploration, visualization, data engineering, and the application of analysis and spatial techniques.

At its core, geospatial technology provides an opportunity to explore location intelligence and how it informs the data we collect. First, the reader will see the relevance of geographic information systems (GIS) and geospatial analytics, revealing the fundamental foundation and capabilities of spatial SQL.

Information and instruction will be formatted as case studies that highlight open source data and analysis across big ideas that you can distill into workable solutions. These vignettes will correlate with an examination of publicly available datasets selected to demonstrate the power of storytelling with geospatial insights.

Open source GIS, combined with PostgreSQL database access and plugins that expand QGIS functionality, have made QGIS integration an important tool for analyzing spatial information.
