Crowdsourcing Geographic Knowledge: Principles and Practice
The process of gathering geographical data supplied by non-expert users and combining it into useful geospatial datasets is known as crowdsourcing of geographic information. Within the context of geospatial data, the term "Volunteered Geographic Information (VGI)" expressedly refers to a dedicated collection effort inviting non-expert users to contribute, even if the term crowdsourcing generally indicates a coordinated bottom-up grassroots effort to provide information. This information, often shared via open platforms like OpenStreetMap or citizen science projects, enriches mapping and spatial databases with diverse, real-time data. VGI can include GPS traces, photos tagged with location, or annotations on digital maps. Its value lies in its immediacy and detail, supplementing traditional data sources like governmental surveys. VGI exemplifies the democratization of geographic information, empowering communities and individuals to actively participate in mapping and influencing decision-making processes. The book aims to shed light on some of the unexplored aspects of outsourcing geographic data and the recent researches in this field. The various advancements in Volunteered Geographic Information are glanced at and their applications as well as ramifications are looked at in detail. Scientists and students actively engaged in this field will find this book full of crucial and unexplored concepts.

The phenomenon of volunteered geographic information is part of a profound transformation in how geographic data, information, and knowledge are produced and circulated. By situating volunteered geographic information (VGI) in the context of big-data deluge and the data-intensive inquiry, the 20 chapters in this book explore both the theories and applications of crowdsourcing for geographic knowledge production with three sections focusing on 1). VGI, Public Participation, and Citizen Science; 2). Geographic Knowledge Production and Place Inference; and 3). Emerging Applications and New Challenges. This book argues that future progress in VGI research depends in large part on building strong linkages with diverse geographic scholarship. Contributors of this volume situate VGI research in geography’s core concerns with space and place, and offer several ways of addressing persistent challenges of quality assurance in VGI. This book positions VGI as part of a shift toward hybrid epistemologies, and potentially a fourth paradigm of data-intensive inquiry across the sciences. It also considers the implications of VGI and the exaflood for further time-space compression and new forms, degrees of digital inequality, the renewed importance of geography, and the role of crowdsourcing for geographic knowledge production.
European Handbook of Crowdsourced Geographic Information
This book focuses on the study of the remarkable new source of geographic information that has become available in the form of user-generated content accessible over the Internet through mobile and Web applications. The exploitation, integration and application of these sources, termed volunteered geographic information (VGI) or crowdsourced geographic information (CGI), offer scientists an unprecedented opportunity to conduct research on a variety of topics at multiple scales and for diversified objectives. The Handbook is organized in five parts, addressing the fundamental questions: What motivates citizens to provide such information in the public domain, and what factors govern/predict its validity? What methods might be used to validate such information? Can VGI be framed within the larger domain of sensor networks, in which inert and static sensors are replaced or combined by intelligent and mobile humans equipped with sensing devices? What limitations are imposed on VGI by differential access to broadband Internet, mobile phones, and other communication technologies, and by concerns over privacy? How do VGI and crowdsourcing enable innovation applications to benefit human society? Chapters examine how crowdsourcing techniques and methods, and the VGI phenomenon, have motivated a multidisciplinary research community to identify both fields of applications and quality criteria depending on the use of VGI. Besides harvesting tools and storage of these data, research has paid remarkable attention to these information resources, in an age when information and participation is one of the most important drivers of development. The collection opens questions and points to new research directions in addition to the findings that each of the authors demonstrates. Despite rapid progress in VGI research, this Handbook also shows that there are technical, social, political and methodological challenges that require further studies and research.
