It equals or surpasses proprietary alternatives, allowing you to create location-aware queries with just a few lines of SQL code, and provides a back-end for mapping applications with minimal effort.PostGIS in Action teaches readers of all levels to write spatial queries that solve real-world problems. It first gives you a background in vector-based GIS and then quickly moves into analyzing, viewing, and mapping data. You'll learn how to optimize queries for maximum speed, simplify geometries for greater efficiency, and create custom functions for your own applications. The book covers PostgreSQL 8.4, 9.0, and 9.1 features and shows you how to integrate with other GIS tools. 目录: Part 1 Learning PostGIS1 What is a spatial database?2 Geometry types3 Organizing spatial data4 Geometry functions5 Relationships between geometries6 Spatial reference system considerations7 Working with real dataPart 2 Putting PostGIS to work8 Techniques to solve spatial problems9 Performance tuningPart 3 Using PostGIS with other tools10 Enhancing SQL with add-ons11 Using PostGIS in web applications12 Using PostGIS in a desktop environmentPostGIS rasterappendix A Additional resourcesappendix B Installing, compiling, and upgradingappendix C SQL primerappendix D PostgreSQL features
