Description
Summary
PostGIS in Action, Second Edition teaches readers of all levels to write spatial queries that solve real-world problems. It first provides you with a background in vector-, raster-, and topology-based GIS and then quickly moves into analyzing, viewing, and mapping data. This second edition covers PostGIS 2.0 and 2.1 series, PostgreSQL 9.1, 9.2, and 9.3 features, and shows you tips on how to integrate with other GIS tools.
Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
About the Book
Processing data tied to location and topology requires specialized know-how. PostGIS is a free spatial database extender for PostgreSQL, each bit as good as proprietary software. With it, you’ll easily create location-aware queries in only some lines of SQL code and build the back end for a mapping, raster analysis, or routing application with minimal effort.
PostGIS in Action, Second Edition teaches you to solve real-world geodata problems. It first provides you with a background in vector-, raster-, and topology-based GIS and then quickly moves into analyzing, viewing, and mapping data. You can discover ways to optimize queries for maximum speed, simplify geometries for greater efficiency, and create custom functions for your own applications. You can also discover ways to apply your existing GIS knowledge to PostGIS and integrate with other GIS tools.
Familiarity with relational database and GIS concepts is helpful but not required.
