Key FeaturesThis easy-to-follow guide allows you to manage and analyze geographic data with ease using open source toolsPublish your geographical data onlineLearn the basics of geoinformatics in a practical way by solving problemsBook DescriptionThe most commonly used GIS tools automate tasks that were historically done manually―compiling new maps by overlaying one on top of the other or physically cutting maps into pieces representing specific study areas, changing their projection, and getting meaningful results from the various layers by applying mathematical functions and operations. This book is an easy-to-follow guide to use the most matured open source GIS tools for these tasks.We'll start by setting up the environment for the tools we use in the book. Then you will learn how to work with QGIS in order to generate useful spatial data. You will get to know the basics of queries, data management, and geoprocessing.After that, you will start to practice your knowledge on real-world examples. We will solve various types of geospatial analyses with various methods. We will start with basic GIS problems by imitating the work of an enthusiastic real estate agent, and continue with more advanced, but typical tasks by solving a decision problem.Finally, you will find out how to publish your data (and results) on the web. We will publish our data with QGIS Server and GeoServer, and create a basic web map with the API of the lightweight Leaflet web mapping library.What you will learnCollect GIS data for your needsStore the data in a PostGIS databaseExploit the data using the power of the GIS queriesAnalyze
