PostGIS in Action, Second Edition teaches readers of all levels to write spatial queries that solve real-world problems. It first gives you a background in vector-, raster-, and topology-based GIS and then quickly moves into analyzing, viewing, and mapping data. This second edition covers PostGIS 2.0 and 2.1 series, PostgreSQL 9.1, 9.2, and 9.3 features, and shows you how to integrate with other GIS tools.
Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
About the Book
Processing data tied to location and topology requires specialized know-how. PostGIS is a free spatial database extender for PostgreSQL, every bit as good as proprietary software. With it, you can easily create location-aware queries in just a few lines of SQL code and build the back end for a mapping, raster analysis, or routing application with minimal effort.
PostGIS in Action, Second Edition teaches you to solve real-world geodata problems. It first gives you a background in vector-, raster-, and topology-based GIS and then quickly moves into analyzing, viewing, and mapping data. You'll learn how to optimize queries for maximum speed, simplify geometries for greater efficiency, and create custom functions for your own applications. You'll also learn how to apply your existing GIS knowledge to PostGIS and integrate with other GIS tools.
Familiarity with relational database and GIS concepts is helpful but not required.

Read everything but ch. 16 & 17. Was not expecting SQL to be such a massive component. I barely know any SQL so it was tough for me to follow, but even despite that I thought that the books examples and language had a lot of jargon that wasn’t explained well for beginners like me. People who have more experience working with PostgreSQL and PostGIS will probably be able to get more out of this book. Not really great for someone like me whose only experience with GIS is working with basic shapefiles and csv files in QGIS. Was hoping for more insights on how to work better in QGIS and I don’t feel like I gained much from this book in that regard. It seems like there’s a lot of powerful things you can do with geospatial data and relational databases in PostgreSQL and PostGIS, but I’ve just never been in a situation where I would use either of those, so it was hard to contextualize a lot of the content that was presented ¯\_(ツ)_/¯
