QGIS:Becoming a GIS Power User

By: Ben Mearns, Alex Mandel, Alexander Bruy, Anita Graser, Víctor Olaya Ferrero

Overview of this book

The first module Learning QGIS, Third edition covers the installation and configuration of QGIS. You’ll become a master in data creation and editing, and creating great maps. By the end of this module, you’ll be able to extend QGIS with Python, getting in-depth with developing custom tools for the Processing Toolbox. The second module QGIS Blueprints gives you an overview of the application types and the technical aspects along with few examples from the digital humanities. After estimating unknown values using interpolation methods and demonstrating visualization and analytical techniques, the module ends by creating an editable and data-rich map for the discovery of community information. The third module QGIS 2 Cookbook covers data input and output with special instructions for trickier formats. Later, we dive into exploring data, data management, and preprocessing steps to cut your data to just the important areas. At the end of this module, you will dive into the methods for analyzing routes and networks, and learn how to take QGIS beyond the out-of-the-box features with plug-ins, customization, and add-on tools. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: ? Learning QGIS, Third Edition by Anita Graser ? QGIS Blueprints by Ben Mearns ? QGIS 2 Cookbook by Alex Mandel, Víctor Olaya Ferrero, Anita Graser, Alexander Bruy

What you need for this learning path

Module 1:

To follow the exercises in this book, you need QGIS 2.14. QGIS installation is covered in the first chapter and download links for the exercise data are provided in the respective chapters.

Module 2:

You will need:

  • QGIS 2.10
  • A computer running OS X, Windows, or Linux

Module 3:

We recommend installing QGIS 2.8 or later; you will need at least QGIS 2.4. During the writing of this book, several new versions were released, approximately every 4 months, and most recently, 2.14 was released. Most of the recipes will work on older versions, but some may require 2.6 or newer. In general, if you can, upgrade to the latest stable release or Long Term Support (LTS) version.

There are also a lot of side interactions with other software throughout many of these

recipes, including—but not limited to—Postgis 2+, GRASS 6.4+, SAGA 2.0.8+, and Spatialite 4+. On Windows, most of these can be installed using OSGeo4W; on Mac, you may need some additional frameworks from Kyngchaos, or if you’re familiar with Brew, you can use the OSGeo4Mac Tap. For Linux users, in particular Ubuntu and Debian, refer to the UbuntuGIS PPA and the DebianGIS blend.

Does all of this sound a little too complicated? If yes, then consider using a virtual machine that runs OSGeo-Live (http://live.osgeo.org). All the software is preinstalled for you and is known to work together.

Lastly, you will need data. For the most part, we’ve provided a lot of free and open data

from a variety of sources, including the OSGeo Educational dataset (North Carolina), Natural Earth Data, OpenFlights, Wake County, City of Davis, and Armed Conflict Location & Event Data Project (ACLED). A full list of our data sources is provided here if you would like additional data.

We recommend that you try methods with the sample data first, only because we tested it.

Feel free to try using your own data to test many of the recipes; however, just remember that you might need to alter the structure to make it work. After all, that’s what you’ll be working with normally.

The following are the data sources for this book:
