Overview of this book

<p><span id="description" class="sugar_field">QGIS is a user-friendly open source geographic information system (GIS) that runs on Linux, Unix, Mac OS X, and Windows. The popularity of open source geographic information systems and QGIS in particular has been growing rapidly over the last few years. This video is a practical, hands-on course updated for QGIS 2.14 that provides you with clear, step-by-step exercises to help you apply your GIS knowledge to QGIS.</span></p> <p><span id="description" class="sugar_field">This video takes you from installing and configuring QGIS to handling spatial data to creating great maps. You will learn how to load and visualize existing spatial data and create data from scratch. You will get to know important plugins, perform common geoprocessing and spatial analysis tasks, and automate them with processing. We will cover how to achieve great cartographic output and print maps. Finally, you will learn how to extend QGIS using Python and even create your own plugin.</span></p> <h2><span class="sugar_field">Style and Approach</span></h2> <p><span class="sugar_field"><span id="trade_selling_points_c" class="sugar_field">This video takes a step-by-step approach to explain the concepts of Geospatial map with the help of real-life examples.

Topological errors can beparticularly annoying, since they can lead to a multitude of different problems. Let’s see how we could resolve these. - Find errors with the Topological checker - Fix invalid geometry errors
