Overview of this book

QGIS 3.4 is the first LTR (long term release) of QGIS version 3. This is a giant leap forward for the project with tons of new features and impactful changes. Learn QGIS is fully updated for QGIS 3.4, covering its processing engine update, Python 3 de-facto coding environment, and the GeoPackage format. This book will help you get started on your QGIS journey, guiding you to develop your own processing pathway. You will explore the user interface, loading your data, editing, and then creating data. QGIS often surprises new users with its mapping capabilities; you will discover how easily you can style and create your first map. But that’s not all! In the final part of the book, you’ll learn about spatial analysis and the powerful tools in QGIS, and conclude by looking at Python processing options. By the end of the book, you will have become proficient in geospatial analysis using QGIS and Python.

If this is not shown in your QGIS project, navigate to View | Toolbars | Label Toolbar, and click to enable the toolbar. There are eight buttons on this toolbar. In order, these are as follows:

  • Layer Labeling: Clicking on this will open the Layer Styling panel and the label tab by default.
  • Layer Diagram properties: This is where we can control the input to our labels.
  • Highlight pinned labels and diagrams.
  • Pin/unpin labels and diagrams.
