Uncertainty and context pose fundamental challenges in GIScience and geographic research. Geospatial data are imbued with errors (e.g., measurement and sampling) and various types of uncertainty that often obfuscate any understanding of the effects of contextual or environmental influences on human behaviors and experiences. These errors or uncertainties include those attributable to geospatial data measurement, model specifications, delineations of geographic context in space and time, and the use of different spatiotemporal scales and zonal schemes when analyzing the effects of environmental influences on human behaviors or experiences. In addition, emerging sources of geospatial big data – including smartphone data, data collected by GPS, and various types of wearable sensors (e.g., accelerometers and air pollutant monitors), volunteered geographic information, and/ or location- based social media data (i.e., crowd- sourced geographic information) – inevitably contain errors, and their quality cannot be fully controlled during their collection or production. Uncertainty and Context in GIScience and Geography: Challenges in the Era of Geospatial Big Data illustrates how cutting- edge research explores recent advances in this area, and will serve as a useful point of departure for GIScientists to conceive new approaches and solutions for addressing these challenges in future research. The seven core chapters in this book highlight many challenges and opportunities in confronting various issues of uncertainty and context in GIScience and geography, tackling different topics and approaches. The chapters in this book were originally published as a special issue of the International Journal of Geographical Information Science.

Mobility, accessibility, networks, and interactions across space are at the heart of how spaces and places are brought into being and continue to change. In a series of articles that chart the development of thinking about space, place, and transport, this book highlights the role that a geographic perspective has played in transport studies, raises questions about transport policy, and points to additional questions worthy of research. The volume is divided into four parts covering fundamental concepts, individual behaviour in urban spatial context, inter-regional transport and policy issues.

This book seeks to bring together different philosophical, theoretical, and methodological approaches to the study of human mobility within the discipline of geography. With five thematic sections - conceptualizing and analyzing mobility, inequalities of mobility, politics of mobility, decentering mobility, and qualifying abstraction - and 27 substantive chapters by leading researchers in the field, it provides a comprehensive overview of the latest thinking about human mobility and related issues. The contributors discuss mobility issues as diverse as everyday mobilities of young people, migrants and refugees, and sex workers; the relationships between citizenship and mobility; and the potential and pitfalls of big data for understanding mobility. This, coupled with a broad international focus, means that Geographies of Mobility will not only encourage and enrich dialogue on a theme that is of major importance to varied geographic research communities, but will also be of great interest to students and researchers across the wider social sciences. This book was originally published as a special issue of Annals of the American Association of Geographers.

Space-time analysis is a rapidly growing research frontier in geography, GIS, and GIScience. Advances in integrated GPS/GIS technologies, the availability of large datasets (over time and space), and increased capacity to manage, integrate, model and visualize complex data in (near) real time, offer the GIS and geography communities extraordinary opportunities to begin to integrate sophisticated space-time analysis and models in the study of complex environmental and social systems, from climate change to infectious disease transmission. This volume specifically focuses on research frontiers, comparative research, and research and application interactions in this field in the US and China, arguably the two most dynamic loci for this work today. The contributions to this book, by top researchers in China and the US, productively highlight the differences and similarities in approaches and directions for space-time analysis in the two countries. In light of the recent rapid progress in GIScience research on space-time integration in both countries, the book’s focus on research frontiers in these two countries will attract great interest in both countries and in other parts of the world as well as among related disciplines. In addition, the book also explores the impact of collaborative research and publications underway in this area between the US and China and will provide an overview of these collaborative efforts and programs. This book will not only be of interest to university-based GIS researchers and students, but also to those interested in this new area of research and applications like researchers and developers in business, internet mapping and GIS and location based services (LBS).

This book constitutes the refereed proceedings of the 7th International Conference on Geographic Information Science, GIScience 2012, held in Columbus, OH, USA in September 2012. The 26 full papers presented were carefully reviewed and selected from 57 submissions. While the traditional research topics are well reflected in the papers, emerging topics that involve new research hot-spots such as cyber infrastructure, big data, web-based computing also occupy a significant portion of the volume.

This book is a collection of papers reflecting the latest advances in geographic research on health, disease, and well-being. It spans a wide range of topics, theoretical perspectives, and methodologies - including anti-racism, post-colonialism, spatial statistics, spatiotemporal modeling, political ecology, and social network analysis. Health issues in various regions of the world are addressed by interdisciplinary authors, who include scholars from epidemiology, medicine, public health, demography, and community studies. The book covers the major themes in this field such as health inequalities; environmental health; spatial analysis and modeling of disease; health care provision, access, and utilization; health and wellbeing; and global/transnational health and health issues in the global south. There is also a specially commissioned book review in addition to the chapters included in these six sections. Together, these chapters show cogently how geographic perspectives and methods can contribute in significant ways to advancing our understanding of the complex interactions between social and physical environments and health behaviors and outcomes. This book was published as a special issue of Annals of the Association of American Geographers.
