PostGIS in Action, Third Edition shows you how to solve real-world geodata problems. Youll go beyond basic mapping, and explore custom functions for your applications.SummaryIn PostGIS in Action, Third Edition you will learn:An introduction to spatial databasesGeometry, geography, raster, and topology spatial types, functions, and queriesApplying PostGIS to real-world problemsExtending PostGIS to web and desktop applicationsQuerying data from external sources using PostgreSQL Foreign Data WrappersOptimizing queries for maximum speedSimplifying geometries for greater efficiencyPostGIS in Action, Third Edition teaches readers of all levels to write spatial queries for PostgreSQL. Youll start by exploring vector-, raster-, and topology-based GIS before quickly progressing to analyzing, viewing, and mapping data. This fully updated third edition covers key changes in PostGIS 3.1 and PostgreSQL 13, including parallelization support, partitioned tables, and new JSON functions that help in creating web mapping applications.Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.About the technologyPostGIS is a spatial database extender for PostgreSQL. It offers the features and firepower you need to take on nearly any geodata task. PostGIS lets you create location-aware queries with a few lines of SQL code, then build the backend for mapping, raster analysis, or routing application with minimal effort.About the bookPostGIS in Action, Third Edition shows you how to solve real-world geodata problems. Youll go beyond basic mapping, and explore custom functions for your applications. Inside this fully updated edition, youll find coverage of new PostGIS features such as PostGIS Window functions, parallelization of queries, and outputting data for applications using JSON and Vector Tile functions.What's insideFully revised for PostGIS version 3.1 and PostgreSQL 13Optimize queries for maximum speedSimplify geometries for greater efficiencyExtend PostGIS to web and desktop applicationsAbout the readerFor readers familiar with relational databases and basic SQL.
