Overview of this book

<p>This course is part of an entire curriculum based on free and open source GIS (FOSS4g) software. The curriculum is grouped into different categories of the FOSS4g stack - Desktop, Server, and Developer. As part of this course, you will learn the most popular open source database - Postgres 11. </p><p>You’ll start with the basics of Postgres, explore PostGIS as a spatial plugin, and then go on to solve spatial problems using SQL. The course uses real data from Tompkins County, New York, and seamlessly integrates with other gisadvisor courses that will teach you QGIS, GDAL, GeoServer, and Python. You'll also explore the capabilities of SQL, working with raster, vector, and attribute data. After you’ve learned SQL and spatial SQL, you’ll understand how to simulate real-world examples of GIS projects and spatial analysis. </p><p>By the end of this course, you will be well-versed with the FOSS4g stack and be equipped with the skills you need for everything from conducting spatial analysis to solving spatial problems using SQL. </p><p>All the codes and supporting files for this course are available at: https://github.com/PacktPublishing/Learning-the-FOSS4g-Stack-Spatial-SQL-with-Postgres-PostGIS</p>

Section 1
SELECT Statements (and their variants)
The SELECT statement is the bread and butter of SQL. And while you'll learn that there is so much more to SQL than the SELECT statement (INSERTS, UPDATES, VALUES, etc.), you are going to want to master the SELECT statement. So, in this lecture we'll explore several ways to utilize the SELECT statement.
