PostGIS in Action First Edition
There is a newer edition of this item:
Purchase options and add-ons
PostGIS in Action is the first book devoted entirely to PostGIS. It will help both new and experienced users write spatial queries to solve real-world problems. For those with experience in more traditional relational databases, this book provides a background in vector-based GIS so you can quickly move to analyzing, viewing, and mapping data. Advanced users will learn how to optimize queries for maximum speed, simplify geometries for greater efficiency, and create custom functions suited specifically to their applications. It also discusses the new features available in PostgreSQL 9.0 /9.1 and PostGIS 2.0 and provides tutorials on using additional open source GIS tools in conjunction with PostGIS.

Editorial Reviews
From the Inside Flap
documentation does a good job of introducing you to the myriad of functions available
in PostGIS and provides examples on how to use each. It won't tell you how to
combine all these functions into a recipe to solve your problems. That is the purpose
of our book. Although it doesn't cover all functions available in PostGIS, this book
does cover the more commonly used or interesting ones and gives you the skills you
need to combine them to solve classic and more esoteric but interesting problems in
spatial analysis and modeling.
While you can use this book as a source of reference, we recommend that you do
visit the official PostGIS site and download or peruse the documentation.
This book focuses on two-dimensional non-curved Cartesian vector geometries.
Although it is primarily about writing spatial queries against 2D vector geometries, we
provide introductions to the following ancillary topics:
- Creating 3D vector geometries
- Creating curved geometries
- Creating and querying the geodetic geography data type
- Working with raster data using the companion raster data type (integrated in
PostGIS 2.0)
if we neglected to provide some perspective on the landscape it lives in. PostGIS is
not an island and rarely works alone. To complete the cycle, we also include the following:
- An extensive appendix that covers PostgreSQL in great detail from setup, to
backup, to security management, as well as the fundamentals of SQL and creating
functions and other objects in it - Several chapters dedicated to the use of PostGIS in web mapping, viewing using
desktop tools, PostgreSQL PL languages commonly used with PostGIS, and extra
open source add-ons such as the TIGER geocoder, pgRouting, PL/R, and PL/
Python
From the Back Cover
- An introduction to spatial databases
- Geometry types, functions, and queries
- Applying PostGIS to real-world problems
- Extending PostGIS to web and desktop applications
but not required.

This is the first book with an in-depth and comprehensive approach to the subject. Although PG has a complete on-line documentation, and a growing community, it is useful to have all this stuff packed for ready use. Being an interdisciplinar matter , mastering it requires ,at least, an elementary knowledge of a computer language - SQL - plus fundamentals of cartography and geodesics - projections, datums geographical coordinate systems - and also the basics of geographical analysis - geometrical operations and computations between polygons, lines and points.
So, it is really hard stuff, and i think the authors suceeded to present all this material in a organized and readable way.
I have a background on traditional GIS packages - like ArcView and ArcMap, and i would recommend this book for anyone triyng - as i am - to learn new approaches on geodatabase management and Geographical Analysis.Being a new an interdisciplinary subject,there is a considerable learning curve, but the authors provide very basic examples to starters, and an excellent appendix full of on-line resources.
developers of all levels of experience. The book is split into three
parts, with the first part containing an excellent overview of
PostGIS, explaining the whys and hows of spatial data and geometries.
The second part then takes the developer through the details of using
PostGIS, including some good coverage of performance pitfalls and
optimisation techniques. Finally, the third part of the book shows how
to integrate PostGIS with other tools.
Part 1 of PostGIS starts off nice and slow, taking the reader through
the basics of what a spatial database is, what geometry data types are
and how they are used in PostGIS. As a traditional SQL developer, I
found this introduction to be very easy to follow. The first part is
rounded out by a useful summary of the tools available to load data
from other, third-party systems into PostGIS and various export
options which are available.
Part 2 of the book is where you learn how to put PostGIS to work.
Techniques discussed include proximity analysis, geocoding addresses,
manipulating polygons and lines, and scaling and rotating geometries.
There is also a very good chapter on performance tuning, which covers
how the PostGIS query planner works, giving very useful information on
how to write efficient queries and how to tune your database and
selection of appropriate indexes and keys for your data. A discussion
on common SQL patterns and their performance implications is included
here and the advice provided is very welcome.
Part 3 covers most of the tools commonly used to build PostGIS
applications. From add-ons used to help with your spatial queries,
through using PostGIS with popular, server-side web-mapping tools
(including Google Maps and Bing Maps) on to open-source desktop tools
supporting PostGIS, this section gives the reader a thorough grasp of
just what tools are available and how they can be used.
Rounding out the book are a nice set of appendices which point you to
various PostGIS resources online, explain how to install PostGIS on
your server and a SQL primer to help you start writing queries.
Overall this is a very well written, easy to follow book that works
equally as well for beginners to PostGIS as it does for advanced
PostGIS developers. Common mistakes are pointed out throughout the
text and the examples provided are clear and to the point. I cannot
recommend this book highly enough to anyone interested in using
PostGIS in their projects, or even those who just want to understand
what a spatial database is all about.
