Overview of this book

QGIS is a user-friendly, cross-platform desktop geographic information system used to make maps and analyze spatial data. QGIS allows users to understand, question, interpret, and visualize spatial data in many ways that reveal relationships, patterns, and trends in the form of maps. This book is a collection of simple to advanced techniques that are needed in everyday geospatial work, and shows how to accomplish them with QGIS. You will begin by understanding the different types of data management techniques, as well as how data exploration works. You will then learn how to perform classic vector and raster analysis with QGIS, apart from creating time-based visualizations. Finally, you will learn how to create interactive and visually appealing maps with custom cartography. By the end of this book, you will have all the necessary knowledge to handle spatial data management, exploration, and visualization tasks in QGIS.

Creating custom SVG graphics

This recipe is all about making your map unique by creating custom icons, north arrows, or even fill patterns.

Getting ready

You will need a vector illustration program (for example, Inkscape or Adobe Illustrator).

You will also need a text editor, such as TextEdit (Mac), Notepad, Notepad++ (Windows).

How to do it…

  1. Open up your vector illustration program.

  2. Set the canvas to a reasonable size to work with. Square ratios tend to work well because the icon will eventually be used to mark points in QGIS; 100x100 pixels is fine.

  3. Draw a simple shape such as a square, circle, or star. Make sure you go most of the way towards the edges and fill the whole page.
