Be aware, though, that this book is squarely aimed at advanced Python users. It assumes the user is already well experienced in the programming language, so a novice will likely have difficulty understanding the concepts and following the processes of the many and sometimes very long scripts presented throughout the book.
Despite this, the author is quite thorough in explaining the purpose of each part of every program and how it is relevant to the process. The book is formatted to give a well-rounded base of GIS processing using Python scripting, and it does so by first introducing the concepts, then trying out some basic techniques, and finally building up to a more complex and complete mapping application. When finished, the user should be ready to create his own Python scripts for GIS applications.
If you are already a strong GIS user who is not a programmer, I would not advise this book; it is not written for this audience. However, if you are familiar and comfortable writing complex Python scripts, this book will give you a very good introduction to geospatial concepts and applications, and I would highly recommend it.
In Building Mapping Applications with QGIS, Erik has created a comprehensive guide through all the steps required to create QGIS plugins and standalone Python applications which utilise the QGIS libraries. It’s not a beginner’s guide to Python or to PyQGIS, but that’s what helps it stand out. There’s no introductory chapters on programming with Python or how to use QGIS and instead Erik dives straight into the meat of this topic. I found this approach really refreshing, as I’m often frustrated when the first few chapters of an advanced work just cover the basics. Instead, Building Mapping Applications with QGIS is packed with lessons about, well, actually building mapping applications!
So, why do I like this book so much? Personally, I think it fills a a really crucial void in the existing QGIS literature. There’s a lot of works covering using QGIS, and a few covering PyQGIS development (eg, the PyQGIS Programmer’s Guide, which I reviewed here). But to date, there hasn’t been any literature that covers developing QGIS based applications in such great depth. It’s just icing on the cake that Erik’s writing is also so interesting and easy to read.
