I thought PostGIS was used for mapping, this book showed me how much PostGIS is actually able to do, and how easy it is to work with it.

PostGIS in Action, Third Edition teaches readers of all levels to write spatial queries for PostgreSQL. It first gives you a background in vector-, raster-, and topology-based GIS and then quickly moves into analyzing, viewing, and mapping data. This fully updated third edition covers key changes in PostGIS 3.0 and PostgreSQL 12, including parallelization support, partitioned tables, and new JSON functions that help in creating web mapping applications.
about the technology
Processing location and topology data requires specialized know-how. PostGIS is a free spatial database extender for PostgreSQL that delivers the features and firepower you need to take on nearly any geodata task. 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.about the book
