Geocomputation with Python is a comprehensive resource for working with geographic data with the most popular programming language in the world. The book gives an overview of Python's capabilities for spatial data analysis, as well as dozens of worked-through examples covering the entire range of standard GIS operations. A unique selling point of the book is its cohesive and joined-up coverage of both vector and raster geographic data models and consistent learning curve. This book is an excellent starting point for those new to working with geographic data with Python, making it ideal for students and practitioners beginning their journey with Python.Key features:Showcases the integration of vector and raster datasets operations.Provides explanation of each line of code in the book to minimize surprises.Includes example datasets and meaningful operations to illustrate the applied nature of geographic research.Another unique feature is that this book is part of a wider community. Geocomputation with Python is a sister project of Geocomputation with R (Lovelace, Nowosad, and Muenchow 2019), a book on geographic data analysis, visualization, and modeling using the R programming language that has numerous contributors and an active community.The book teaches how to import, process, examine, transform, compute, and export spatial vector and raster datasets with Python, the most widely used language for data science and many other domains. Reading the book and running the reproducible code chunks within will make you a proficient user of key packages in the ecosystem, including shapely, geopandas, and rasterio. The book also demonstrates how to make use of dozens of additional packages for a wide range of tasks, from interactive map making to terrain modeling. Geocomputation with Python provides a firm foundation for more advanced topics, including spatial statistics, machine learning involving spatial data, and spatial network analysis, and a gateway into the vibrant and supportive community developing geographic tools in Python and beyond.

This book takes you through every stage you need to create superb maps using QGIS 2.0 – from installation on your favorite OS to data editing and spatial analysis right through to designing your print maps.Key FeaturesLoad and visualize vector and raster dataCreate and edit spatial data and perform spatial analysisConstruct great maps and print themBook DescriptionQGIS is a user friendly open source geographic information system (GIS) that runs on Linux, Unix, Mac OSX, and Windows. The popularity of open source geographic information systems and QGIS in particular has been growing rapidly over the last few years. More and more companies and institutions are adopting QGIS and even switching to QGIS as their main GIS.Learning QGIS 2.0 is a practical, hands-on guide that provides you with clear, step-by-step exercises that will help you to apply your GIS knowledge to QGIS. Containing a number of clear, practical exercises, this book will introduce you to working with QGIS, quickly and painlessly. If you want to take advantage of the wide range of functionalities that QGIS offers, then this is the book for you.This book takes you from installing and configuring QGIS, through handling spatial data to creating great maps. You will learn how to load and visualize existing spatial data and how to create data from scratch. You will perform common geoprocessing and spatial analysis tasks and automate them. We will cover how to achieve great cartographic output and print maps. You will learn everything you need to know to handle spatial data management, processing, and visualization tasks in QGIS.What you will learnInstalling QGISGetting comfortable with the QGIS user interfaceLoading vector and raster data from files, databases, and web servicesCreating, editing, and visualizing spatial dataPerforming geoprocessing tasksAutomating geoprocessing and spatial analysis tasksCreating advanced cartographic outputDesigning great print mapsWho this book is forThis book is great for users, developers, and consultants who know the basic functions and processes of a GIS but want to know how to use QGIS to achieve the results they are used to a full-fledged GIS.

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.
