PostGIS in Action, Third Edition teaches you to solve real-world
geodata problems. It first gives you a background in vector-,
raster-, and topology-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.
You'll also learn how to apply your existing GIS knowledge to
PostGIS and integrate with other GIS tools. Fully updated to the
latest versions of PostGIS and PostgreSQL, this Third Edition
covers new PostGIS features including Foreign Data Wrappers,
Database as a Service, parallelization of queries, and new JSON and
Vector Tiles functions that help in creating web mapping
applications. Key Features * An introduction to spatial databases *
