qgis for beginners: Textbook on Spherical Astronomy W. M. Smart, 1977-07-07 This well-established textbook gives a general but comprehensive introduction to positional astronomy. Originally based on the author's lecture courses at Cambridge University, it is intended primarily for undergraduates, but, due to its comprehensive nature, it is a very useful reference text for research workers in many branches of astronomy and space physics. The author considers the night sky as the celestial sphere and powerfully exploits the methods of spherical geometry. Most problems in which the precise determination of a heavenly body's position in the sky is important are considered in theoretical detail, and the necessary formulae are derived to a precision that is sufficient for all but the most specialist purposes. The present revision has ensured that the terminology and treatment correspond precisely to current astronomical practice. A guiding principle has been to re-establish compatibility with the Astronomical Ephemeris and, to a lesser extent, with the fuller explanations of the Explanatory Supplement to the Astronomical Ephemeris and the American Ephemeris and Nautical Almanac. Fairly frequent comments added to the text indicate the sometimes modified relevance of the subject matter to modern astronomy. A number of additional exercises help to illustrate the new material. |

qgis for beginners: Handling of Geospatial Data with QGIS Ko Ko Lwin, Yuji Murayama, 2025-05-08 This textbook introduces QGIS software and shows how to use it step-by-step using many illustrations. Some topics can be understood by viewing a figure, without the need to read texts. The purposes, functions, and potential applications of the software are also explained. The book is a good first step to understand the theories on GIS through practice. With the increasing use of GIS (geographic information systems/science) in the arenas of education and research, the need for this book is becoming apparent. Students and researchers in various disciplines have noted that GIS is a powerful tool for acquiring, exploring, analyzing, and visualizing geospatial data for their work. Some of their data come from geospace in the form of coordinates; of course, we are living in a world with coordinates. Wherever we move, whatever we do, we can be located by coordinates, as everything is at rest, moving, or happening in space. Although GIS has been used for a long time in many professional fields, such as land surveying, urban and regional development, transportation planning, hydrology, environmental management, and so on, the use of GIS by the public is fairly recent. Following the emergence of global positioning systems, wireless communication technologies, and nano-scale microchip technologies, GIS is now a commonplace. Together with advanced technologies and user-friendly software development, the use of GIS has moved from desktop to laptop to mobile devices, and from professionals to academics to the public. Moreover, QGIS is increasingly used by students, researchers, and professionals on a daily basis due to its free and open-source geographic information system, community-based software development, user-friendliness, and the many plugins that are available to enhance the capabilities of this software. |
qgis for beginners: PostGIS in Action Regina Obe, Leo Hsu, 2011-05-01 Whether you're canvassing a congressional district, managing a sales region, mapping city bus schedules, or analyzing local cancer rates, thinking spatially opens up limitless possibilities for database users. PostGIS, a freely available open-source spatial database extender, can help you answer questions that you could not answer using a mere relational database. Its feature set equals or surpasses proprietary alternatives, allowing you to create location-aware queries and features with just a few lines of SQL code. PostGIS in Action is the first book devoted entirely to PostGIS. It will help both new and experienced users write spatial queries to solve real-world problems. For those with experience in more traditional relational databases, this book provides a background in vector-based GIS so you can quickly move to analyzing, viewing, and mapping data. Advanced users will learn how to optimize queries for maximum speed, simplify geometries for greater efficiency, and create custom functions suited specifically to their applications. It also discusses the new features available in PostgreSQL 8.4 and provides tutorials on using additional open source GIS tools in conjunction with PostGIS. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book. |

qgis for beginners: Qgis Favour Williams, 2022-11-09 About This Book It covers the basics of QGIS, gives examples, and then guides you through a working project of mapping out an area to allow you to understand and master the basics of GIS and cartography. Shows where to get free data and how to check that data for validity. While this book teaches GIS via the open source program of Quantum GIS, it is applicable to any GIS program. In Detail QGIS is the leading alternative to proprietary GIS software. Although QGIS is described as intuitive, it is also, by default, complex. Knowing which tools to use and how to apply them is essential to producing valuable deliverables on time. Starting with a refresher on QGIS basics, this book will take you all the way through to creating your first custom QGIS plugin. By the end of the book, you will understand how to work with all the aspects of QGIS, and will be ready to use it for any type of GIS work. From the refresher, you will learn how to create, populate, and manage a spatial database and walk through styling GIS data, from creating custom symbols and color ramps to using blending modes. In the next section, you will discover how to prepare vector and raster data for processing and discover advanced data creation and editing techniques. The last third of the book covers more technical aspects of QGIS, including working with the Processing Toolbox, how to automate workflows with batch processing, and how to create graphical models. Finally, you will learn how to create and run Python data processing scripts and write your own QGIS plugin with pyqgis. With this book you'll learn about: The QGIS interface Creating, editing, and analyzing vector data Working with raster (image) data Using plugins The QGIS Processing Toolbox Georeferencing Creating map and reports |
