The first book about PostGIS, a lightweight, open source tool that adds

geographic support to the popular PostgreSQL database. PostGIS is

used to develop location-based services.

From mobile phone usage to online shopping and every application in

between, location is an incredibly important piece of data. PostGIS is a

high-caliber, open source tool that allows developers to take location

information and make it actionable.

PostGIS in Action will help both new and experienced database users

solve location-related problems. For those with experience in more

traditional relational databases, this book provides a background in

vector-based GIS so they can quickly move on to analyzing, viewing,

and mapping data. This tutorial includes discussion and examples of

many real-world uses.

• The only book devoted entirely to PostGIS.

• Discusses real-world problems, not academic ones.

• Covers features of PostgreSQL 8.4.
