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.

Raster data

For the main, raster data that you create will be created via processing tools such as interpolation or the gridding of point data. Sometimes, we may want to rasterize a vector layer. This can be done using the Raster | Conversion | Rasterize command.

Let's load the SR_50M_alasak_nad.tif raster into the GeoPackage we have just created. You can just drag the layer in the Browser panel into the GeoPackage. It will show a message box once loaded, as in the following screenshot:

It is that simple to add data to a GeoPackage. Drag this layer into the map to check that it is actually present.
