Hybrid GIS and Linux geeks know that the open-source PostGIS gives support for
geographic objects to PostgreSQL, allowing the relational database to serve as
the back end for ArcGIS, GRASS GIS and other geospatial programs. The new 2nd
edition of PostGIS in Action from Regina O. Obe and Leo S. Hsu teaches
readers of all levels to write spatial queries that solve real-world problems.
Obe and Hsu start by getting readers' feet wet with a background in
vector-, raster- and topology-based GIS, followed by a tutorial in analyzing,
viewing and mapping data. Readers learn how to optimize queries for maximum
speed, simplify geometries for greater efficiency, analyze rasters, vectorize
rasters, better manage data utilizing topologies and create custom functions.
The book covers PostGIS 2.0 and 2.1, PostgreSQL 9.1, 9.2 and 9.3 features and
shows how to integrate PostGIS with other GIS tools.
