By: Andrew Cutts

Overview of this book

QGIS is a user friendly, open source geographic information system (GIS). The popularity of open source GIS and QGIS, in particular, has been growing rapidly over the last few years. This book is designed to help beginners learn about all the tools required to use QGIS 3.4. This book will provide you with clear, step-by-step instructions to help you apply your GIS knowledge to QGIS. You begin with an overview of QGIS 3.4 and its installation. You will learn how to load existing spatial data and create vector data from scratch. You will then be creating styles and labels for maps. The final two chapters demonstrate the Processing toolbox and include a brief investigation on how to extend QGIS. Throughout this book, we will be using the GeoPackage format, and we will also discuss how QGIS can support many different types of data. Finally, you will learn where to get help and how to become engaged with the GIS community.

Plugins in QGIS

We briefly touched on plugins in Chapter 5, Creating Maps. We used qgis2web to convert our Alaska map into a web map. The top plugins by download are listed here: https://plugins.qgis.org/plugins/popular/. You can use this page to search for plugins or look at tags to view the different plugins and their capabilities.

Plugins are accessed via the Plugins menu. Some plugins are experimental. By experimental, we mean they could be unstable or in the early stages of development, but it is worth turning these on in case a plugin is available that might help your workflows; just use them with caution. From the Plugins dialog, choose Settings and check the box next to Show also experimental plugins:
