Preface

QGIS, the world's most popular free/open source desktop geographic information system software, enables a wide variety of use cases involving location—formerly only available through expensive, specialized commercial software. However, designing and executing a multitiered project from scratch on this complex ecosystem remains a significant challenge.

This book starts with a primer on QGIS and closely-related data, software, and systems. We'll guide you through seven use-case blueprints for geographic web applications. Each blueprint boils down a complex workflow into steps that you can follow to reduce the time usually lost to trial and error.

By the end of this book, readers will be able to build complex layered applications that visualize multiple datasets, employ different types of visualization, and give end users the ability to interact with and manipulate this data for the purpose of analysis.
