Whether you're canvassing a congressional district, managing a
sales region, mapping city bus schedules, or analyzing local
cancer rates, thinking spatially opens up limitless possibilities
for database users. PostGIS, a freely available open-source
spatial database extender, can help you answer questions that you
could not answer using a mere relational database. Its feature
set equals or surpasses proprietary alternatives, allowing you to
create location-aware queries and features with just a few lines
of SQL code.

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.
