QGIS 2 Cookbook

By: Mandel, Olaya Ferrero, Anita Graser

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 animations using Time Manager


In this recipe, we will use the Time Manager plugin to create an image series out of our spatiotemporal QGIS project and turn it into a video, which is ready to be uploaded on Youtube or added into a presentation using easily available and free tools.

Getting ready

To follow this recipe, it's advisable that you complete the previous recipe, Exploring spatiotemporal vector data using Time Manager, to set up this project.

To turn the image series exported by Time Manager into a video, we can use external programs, such as the command-line tool Mencoder, or the free Windows Movie Maker.

Mencoder is a very useful command-line tool to encode videos, which is available from repositories for many Linux distributions and for Mac. Windows users can download it from Gianluigi Tiesi's site at http://oss.netfarm.it/mplayer-win32.php.

If you're using Windows, you can also create the video using the free Windows Movie Maker application, which can be downloaded from http...
