Mastering Geospatial Development with QGIS 3.x - Third Edition

Overview of this book

QGIS is an open source solution to GIS and widely used by GIS professionals all over the world. It is the leading alternative to proprietary GIS software. Although QGIS is described as intuitive, it is also, by default, complex. Knowing which tools to use and how to apply them is essential to producing valuable deliverables on time. Starting with a refresher on the QGIS basics and getting you acquainted with the latest QGIS 3.6 updates, this book will take you all the way through to teaching you how to create a spatial database and a GeoPackage. Next, you will learn how to style raster and vector data by choosing and managing different colors. The book will then focus on processing raster and vector data. You will be then taught advanced applications, such as creating and editing vector data. Along with that, you will also learn about the newly updated Processing Toolbox, which will help you develop the advanced data visualizations. The book will then explain to you the graphic modeler, how to create QGIS plugins with PyQGIS, and how to integrate Python analysis scripts with QGIS. By the end of the book, you will understand how to work with all aspects of QGIS and will be ready to use it for any type of GIS work.

Creating 3D views 


Starting from QGIS 3, QGIS now has its own 3D views capable and built-in instead of resorting to the assistance of any plugins. You can create 3D views by clicking on View | New 3D Map View.

Here, we will use the QGIS terrain.qgs project to generate a view of the Sandia Mountains outside Albuquerque, NM. The project has two layers: a styled Digital Elevation Model (DEM), and a hillshade layer. The hillshade layer has been set up with a multiply blending mode to create a color hillshade effect.

To generate the 3D view, follow these steps:

  1. From the menu bar, select View | New 3D Map Layer.
  2. Now, we will see that a 3D map of this is generated inside a new window as follows:
  1. Now, to see it in 3D view, hold down the Shift key on the keyboard and move your mouse left or right to rotate this. Similarly, by holding down the Shift key and moving the mouse upward or downward, you can tilt it upward or downward.
