Book Description
One of the most natural representations for modelling spatial objects in computers is discrete representations in the form of a 2D square raster and a 3D cubic grid, since these are naturally obtained by segmenting sensor images. However, the main difficulty is that discrete representations are only approximations of the original objects, and can only be as accurate as the cell size allows. If digitisation is done by real sensor devices, then there is the additional difficulty of sensor distortion. To overcome this, digital shape features must be used that abstract from the inaccuracies of digital representation. In order to ensure the correspondence of continuous and digital features, it is necessary to relate shape features of the underlying continuous objects and to determine the necessary resolution of the digital representation. This volume gives an overview and a classification of the actual approaches to describe the relation between continuous and discrete shape features that are based on digital geometric concepts of discrete structures. Audience: This book will be of interest to researchers and graduate students whose work involves computer vision, image processing, knowledge representation or representation of spatial objects.

Book Description
As digital technologies have become part of everyday life, mediating tasks such as work, travel, consumption, production, and leisure, they are having increasingly profound effects on phenomena that are of immediate concern to geographers. These include: the production of space, spatiality and mobilities; the processes, practices, and forms of mapping; the contours of spatial knowledge and imaginaries; and, the formation and enactment of spatial knowledge politics Similarly, there are distinct geographies of digital media such as those of the internet, games, and social media that have become indispensable to geographic practice and scholarship across sub-disciplines, regardless of conceptual approach. This textbook presents a fully up-to-date, synoptic and critical overview of how digital devices, logics, methods, etc are transforming geography. It is divided into six inter-related sections introduction to digital geographies digital spaces digital methods digital cultures digital economies digital politics With illustrious instructors and researchers contributing to every chapter, Digital Geographies is the ideal textbook for courses concerning digital geographies, digital and new media and Internet communications, and the spatial knowledge of politics.

Book Description
This book collects contributions which showcase the impact of new augmented reality (AR) and artificial intelligence (AI) technologies considered jointly in the fields of cultural heritage and innovative design. AR is an alternative path of analysis and communication if applied to several fields of research, in particular if related to space and artifacts in it. This happens because the neural network development strengthens the relationship between augmented reality and artificial intelligence, creating processes close to human thought in shorter times. In the last years, the AR/AI expansion and the future scenarios have raised a deep trans-disciplinary speculation. The disciplines of representation (drawing, surveying, visual communication), as a convergence place of multidisciplinary theoretical and applicative studies related to architecture, city, environment, tangible and intangible cultural heritage, are called to contribute to the international debate. The book chapters deal with augmented reality and artificial intelligence, analyzing their connections as research tools for knowing the environment. In particular, the topics focus on the intersection between real and virtual world and on the heuristic role of drawing in the enhancement and management of cultural heritage, in planning and monitoring the architecture, the environment, or the infrastructures. Scientists involved in AR and AI research applied separately or together in the field of cultural heritage, architectural design, urban planning, and infrastructures analysis, as well as members of public and private organizations make up interdisciplinary groups that fuel the discussion focusing on the priorities and aims of the research related to the disciplines of representation.

Book Description
In recent years, the science of managing and analyzing large datasets has emerged as a critical area of research. In the race to answer vital questions and make knowledgeable decisions, impressive amounts of data are now being generated at a rapid pace, increasing the opportunities and challenges associated with the ability to effectively analyze this data.

Book Description
Recent advances in information technology have enabled scientists to generate unprecedented amounts of earth-related data, with tremendous potential for dealing with pressing social, economic, and environmental issues. Yet the volume and heterogeneity of available data clearly overwhelm traditional analytical approaches, as well as the human capacity to derive patterns and useful insights. This book examines how geospatial knowledge can be analyzed and represented in a manner that not only is accurate and coherent, but also makes intuitive sense to the end user. Integrating concepts and approaches from geography, computer science, cognitive psychology, and philosophy, Donna J. Peuquet explores the processes by which people acquire, represent, and utilize spatiotemporal knowledge. Arguing that the human user and the computer must be viewed as interrelated components of a single system, she provides principles and recommendations for improving the design of geographic information systems (GIS) and other geospatial modeling tools. An ideal student text or professional reference, this book fills a crucial need in geographic information science.

Book Description
Over the past decade, a new set of interactive, open, participatory and networked spatial media have become widespread. These include mapping platforms, virtual globes, user-generated spatial databases, geodesign and architectural and planning tools, urban dashboards and citizen reporting geo-systems, augmented reality media, and locative media. Collectively these produce and mediate spatial big data and are re-shaping spatial knowledge, spatial behaviour, and spatial politics. Understanding Spatial Media brings together leading scholars from around the globe to examine these new spatial media, their attendant technologies, spatial data, and their social, economic and political effects. The 22 chapters are divided into the following sections: Spatial media technologies Spatial data and spatial media The consequences of spatial media Understanding Spatial Media is the perfect introduction to this fast emerging phenomena for students and practitioners of geography, urban studies, data science, and media and communications.
