Master data management, visualization, and spatial analysis techniques in QGIS and become a GIS power userAbout This Book* Learn how to work with various types of 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* This progressive, hands-on guide builds on a geo-spatial data and adds more reactive maps using geometry tools.Who This Book Is ForIf you are a user, developer, or consultant and want to know how to use QGIS to achieve the results you are used to from other types of GIS, then this learning path is for you. You are expected to be comfortable with core GIS concepts. This Learning Path will make you an expert with QGIS by showing you how to develop more complex, layered map applications. It will launch you to the next level of GIS users.What You Will Learn* Create your first map by styling both vector and raster layers from different data sources* Use parameters such as precipitation, relative humidity, and temperature to predict the vulnerability of fields and crops to mildew* Re-project vector and raster data and see how to convert between different style formats* Use a mix of web services to provide a collaborative data system* Use raster analysis and a model automation tool to model the physical conditions for hydrological analysis* Get the most out of the cartographic tools to in QGIS to reveal the advanced tips and tricks of cartographyIn DetailThe 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, Victor Olaya Ferrero, Anita Graser, Alexander BruyStyle and approachThis Learning Path will get you up and running with QGIS. We start off with an introduction to QGIS and create maps and plugins. Then, we will guide you through Blueprints for geographic web applications, each of which will teach you a different feature by boiling down a complex workflow into steps you can follow. Finally, you'll turn your attention to becoming a QGIS power user and master data management, visualization, and spatial analysis techniques of QGIS.

A fast-paced guide to putting your GeoServer-based application into fast, user-friendly, and secure productionKey FeaturesResolve bottlenecks, optimize data stores, and cluster server resourcesUse identity management and authentication for a user-specific, secure web applicationGo beyond traditional web hosting to explore the full range of hosting options in the cloudBook DescriptionGeoServer is open source, server-side software written in Java that allows users to share and edit geospatial data. In this book, you'll start by learning how to develop a spatial analysis platform with web processing services. Then you'll see how to develop an algorithm by chaining together geospatial analysis processes, which you can share with anyone in the world. Next you'll delve into a very important technique to improve the speed of your map application—tile caching. Here, you'll understand how tile caching works, how to develop an effective tile cache-supported web service, and how to leverage tile caching in your OpenLayers web application.Further on, you'll explore important tweaks to produce a performant GeoServer-backed web mapping application. Moving on, you'll enable authentication on the frontend and backend to protect sensitive map data, and deliver sensitive data to your end user. Finally, you'll see how to put your web application into production in a secure and user-friendly way. You'll go beyond traditional web hosting to explore the full range of hosting options in the cloud, and maintain a reliable server instance.What you will learnDevelop a WPS-processing service to allow web-based geospatial data processingGet to know important techniques to improve the speed of your web map application—tile caching, raster data optimization, and server clusteringFind out which GeoServer settings resolve bottlenecksDevelop an algorithm by chaining geospatial analysis processes togetherPut your application into production with hosting, monitoring, and automated backup and recoveryUnderstand how to develop an effective tile cache-supported web serviceMaster techniques that ensure resilient server deploymentWho this book is forThis book is for anyone who wants to learn about advanced interfaces, security, and troubleshooting techniques in GeoServer. A basic understanding of GeoServer is required
