PostGIS in Action


This book is not a replacement for the state PostGIS documentation. The official PostGIS documentation does a good job of introducing us to the many functions available in PostGIS and offers examples on how to use each. It will not show us the best way to combine each one of these functions right into a recipe to resolve your problems. That's the purpose of our book. Though it doesn't cover all functions obtainable in PostGIS, this book does cover the harder commonly used or interesting ones and provides the skills you must combine the crooks to solve classic plus more esoteric but interesting problems in spatial analysis and modeling.

Whilst we can use this book being a source of reference, It is recommend that we are doing go to the official PostGIS site and download or peruse the documentation.

This book focuses on two-dimensional non-curved Cartesian vector geometries. Though it is primarily about writing spatial queries against 2D vector geometries, this book provide introductions for the following ancillary topics:
  • Creating 3D vector geometries
  • Creating curved geometries
  • Creating and querying the geodetic geography data type
  • Utilizing raster data with all the companion raster data type (integrated in PostGIS 2.0)


While the main purpose of this book will be the use of PostGIS, it is would fall short of the mission if  neglected to provide some perspective for the landscape it lives in. PostGIS is no island and rarely works alone. To finish the cycle, its also include the following:
  • A substantial appendix that covers PostgreSQL in great detail from setup, to backup, to security management, along with the fundamentals of SQL and creating functions as well as other objects inside
  • Several chapters dedicated to the usage of PostGIS in web mapping, viewing using desktop tools, PostgreSQL PL languages widely used with PostGIS, and additional open source add-ons like the TIGER geocoder, pgRouting, PL/R, and PL/Python
