The latest guide to using QGIS 2.14 to create great maps and perform geoprocessing tasks with easeAbout This BookLearn how to work with various data and create beautiful maps using this easy-to-follow guide.Give a touch of professionalism to your maps both for functionality and look and feel with the help of this practical guide.A progressive hands-on guide that builds on a geo-spatial data and adds more reactive maps by using geometry tools.Who This Book Is ForThis book is great for users, developers, and consultants who know the basic functions and processes of GIS and want to learn to use QGIS to analyze geospatial data and create rich mapping applications. If you want to take advantage of the wide range of functionalities that QGIS offers, then this is the book for you.What You Will LearnInstall QGIS and get familiar with the user interfaceLoad vector and raster data from files, databases, and web servicesCreate, visualize, and edit spatial dataPerform geoprocessing tasks and automate themCreate advanced cartographic outputsDesign great print mapsExpand QGIS using PythonIn DetailQGIS 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.Learning QGIS Third Edition is a practical, hands-on guide updated for QGIS 2.14 that provides you with clear, step-by-step exercises to help you apply your GIS knowledge to QGIS. Through clear, practical exercises, this book will introduce you to working with QGIS quickly and painlessly.This book 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.Style and approachA step by step approach to explain concepts of Geospatial map with the help of real life examples
