Computer Applications in Geography


Book Description

Computer Applications in Geography Paul M. Mather Department of Geography, University of Nottingham, England Geography graduates are expected to be computer literate, yet the literature on computing is often inaccessible to them. This book is intended for undergraduate students of geography who wish to familiarise themselves with the terminology of computers and to read about the ways in which computers are presently being used in geography. It assumes no prior knowledge of computers and no mathematical skills beyond those possessed by the average layman. The first two chapters form a technical introduction to computers and data. The remaining five chapters are devoted to individual topics representing a selection of the main areas of computer use in geography and show how computers can be used to acquire, process and display geographical data. Worked examples, with example data sets, are given for three program packages that are widely used by geographers--SPSS, SYMAP and GIMMS. The book is comprehensive in its coverage of the major areas of computer applications and will be of interest to geographers dealing with statistics, digital cartography, remote sensing, geographical information systems and simulation models.




Geography and Technology


Book Description

This volume celebrates the 100th anniversary of the Association of American Geographers. It recognizes the importance of technologies in the production of geographical knowledge. The original chapters presented here examine technologies that have affected geography as a discipline. Among the technologies discussed are cartography, the camera, aerial photography, computers, and other computer-related tools. The contributors address the impact of such technologies on geography and society, disciplinary inquiries into the social/technological interfaces, high-tech as well low-tech societies, and applications of technologies to the public and private sectors. Geography and Technology can be used as a textbook in geography courses and seminars investigating specific technologies and the impacts of technologies on society and policy. It will also be useful for those in the humanities, social, policy and engineering sciences, planning and development fields where technology questions are becoming of increased importance. Geography clearly has much to learn from other disciplines and fields about geography/technology linkages; others can likewise learn much from us.




Spatial Computing


Book Description

An accessible guide to the ideas and technologies underlying such applications as GPS, Google Maps, Pokémon Go, ride-sharing, driverless cars, and drone surveillance. Billions of people around the globe use various applications of spatial computing daily—by using a ride-sharing app, GPS, the e911 system, social media check-ins, even Pokémon Go. Scientists and researchers use spatial computing to track diseases, map the bottom of the oceans, chart the behavior of endangered species, and create election maps in real time. Drones and driverless cars use a variety of spatial computing technologies. Spatial computing works by understanding the physical world, knowing and communicating our relation to places in that world, and navigating through those places. It has changed our lives and infrastructures profoundly, marking a significant shift in how we make our way in the world. This volume in the MIT Essential Knowledge series explains the technologies and ideas behind spatial computing. The book offers accessible descriptions of GPS and location-based services, including the use of Wi-Fi, Bluetooth, and RFID for position determination out of satellite range; remote sensing, which uses satellite and aerial platforms to monitor such varied phenomena as global food production, the effects of climate change, and subsurface natural resources on other planets; geographic information systems (GIS), which store, analyze, and visualize spatial data; spatial databases, which store multiple forms of spatial data; and spatial statistics and spatial data science, used to analyze location-related data.




Geography and Technology


Book Description

It is particularly appropriate that the AAG's Centennial Celebration should prompt the publication of a volume devoted to Geography and Technology. New technologies have always been important in advancing geographic understanding, but never have they been so thoroughly and rapidly transformative of the discipline as at this stage in geography's evolution. Just as new technologies have profoundly expanded both research possibilities and the knowledge base of other disciplines, such as biology, physics or medicine, so too are the revolutionary new geographic technologies developed during the past few decades extending frontiers in geographic research, education and applications. They are also creating new and resurgent roles for geography in both society and in the university. This trend is still accelerating, as the integration of geographic technologies, such as the global positioning system and geographic information systems (GPS/GIS), is creating an explosion of new "real-time, real-world" applications and research capabilities. The resultant dynamic space/time interactive research and management environments created by interactive GPS/GIS, among other technologies, places geography squarely at the forefront of advanced multidisciplinary research and modeling programs, and has created core organization management tools (geographic management systems) which will dramatically change the way governments and businesses work in the decades ahead. While these and other important geographic technologies, including remote sensing, location-based services, and many others addressed in this book, are forging new opportunities for geography and geographers, they also pose challenges.




Charting the Unknown


Book Description

Many, like Chrisman, have since become leaders in GIS-related education, research, and software engineering. Illustrated with numerous maps, drawings, diagrams, and photos, Charting the Unknown's twelve chapters are supplemented with a CD that contains three historic short films showing animated visualization. In addition, the CD contains videotaped interviews and a speech featuring some of the Lab's key figures, including Allan Schmidt, former executive director of the Lab; Eric Teicholz, founder and president of Graphic Systems; Jack Dangermond, founder and president of ESRI; Scott Morehouse, director of software development at ESRI; as well as the author.




Geocomputation with R


Book Description

Geocomputation with R is for people who want to analyze, visualize and model geographic data with open source software. It is based on R, a statistical programming language that has powerful data processing, visualization, and geospatial capabilities. The book equips you with the knowledge and skills to tackle a wide range of issues manifested in geographic data, including those with scientific, societal, and environmental implications. This book will interest people from many backgrounds, especially Geographic Information Systems (GIS) users interested in applying their domain-specific knowledge in a powerful open source language for data science, and R users interested in extending their skills to handle spatial data. The book is divided into three parts: (I) Foundations, aimed at getting you up-to-speed with geographic data in R, (II) extensions, which covers advanced techniques, and (III) applications to real-world problems. The chapters cover progressively more advanced topics, with early chapters providing strong foundations on which the later chapters build. Part I describes the nature of spatial datasets in R and methods for manipulating them. It also covers geographic data import/export and transforming coordinate reference systems. Part II represents methods that build on these foundations. It covers advanced map making (including web mapping), "bridges" to GIS, sharing reproducible code, and how to do cross-validation in the presence of spatial autocorrelation. Part III applies the knowledge gained to tackle real-world problems, including representing and modeling transport systems, finding optimal locations for stores or services, and ecological modeling. Exercises at the end of each chapter give you the skills needed to tackle a range of geospatial problems. Solutions for each chapter and supplementary materials providing extended examples are available at https://geocompr.github.io/geocompkg/articles/.

Atmospheres and Oceans on Computers


Book Description

This textbook introduces step by step the basic numerical methods to solve the equations governing the motion of the atmosphere and ocean, and describes how to develop a set of corresponding instructions for the computer as part of a code. Today's computers are powerful enough to allow 7-day forecasts within hours, and modern teaching of the subject requires a combination of theoretical and computational approaches. The presentation is aimed at beginning graduate students intending to become forecasters or researchers, that is, users of existing models or model developers. However, model developers must be well versed in the underlying physics as well as in numerical methods. Thus, while some of the topics discussed in the modeling of the atmosphere and ocean are more advanced, the book ensures that the gap between those scientists who analyze results from model simulations and observations and those who work with the inner works of the model does not widen further. In this spirit, the course presents methods whereby important balance equations in oceanography and meteorology, namely the advection-diffusion equation and the shallow water equations on a rotating Earth, can be solved by numerical means with little prior knowledge. The numerical focus is on the finite-difference (FD) methods, and although more powerful methods exist, the simplicity of FD makes it ideal as a pedagogical introduction to the subject. The book also includes suitable exercises and computer problems.
