Issue Mapping for an Ageing Europe is a seminal guide to mapping social and political issues with digital methods. The issue at stake concerns the imminent crisis of an ageing Europe and its impact on the contemporary welfare state. The book brings together three leading approaches to issue mapping: Bruno Latour's social cartography, Ulrich Beck's risk cartography and Jeremy Crampton's critical neo-cartography. These modes of inquiry are put into practice with digital methods for mapping the ageing agenda, including debates surrounding so-called 'old age', cultural philosophies of ageing, itinerant care workers, not to mention European anti-ageing cuisine. Issue Mapping for an Ageing Europe addresses an urgent social issue with new media research tools.

Urban impervious surface (UIS) is a key parameter in climate change, environmental change, and sustainability. UIS extraction has been evolving rapidly in the past decades. However, high-resolution impervious surface mapping is a long-term need. There is an urgent requirement for impervious surface mapping from high-resolution remote sensing imagery. In this paper, we compare current extraction methods in terms of extraction units and extraction models and summarize their strengths and limitations. We discuss the challenges in impervious surface estimation from high spatial resolution remote sensing imagery in terms of selection of spatial resolution, spectral band, and extraction method. The uncertainties caused by clouds and snow, shadows, and vegetation occlusion are also analyzed. Automated sample labeling and remote sensing domain knowledge are the main directions in impervious surface extraction using deep learning methods. We should also focus on using continuous time series of high-resolution imagery and multi-source satellite imagery for dynamic monitoring of impervious surfaces.

Mounting critique of the way AI is framed in mainstream media calls for less sensationalist coverage, be it jubilant or apocalyptic, and more attention to the concrete situations in which AI becomes controversial in different ways. This is supposedly achieved by making coverage more expert-informed. We therefore explore how experts contribute to the issuefication of AI through the scientific literature. We provide a semantic, visual network analysis of a corpus of 1M scientific abstracts about machine learning algorithms and artificial intelligence. Through a systematic quali-quantitative exploration of 235 co-word clusters and a subsequent structured search for 18 issue-specific queries, for which we devise a novel method with a custom-built datascape, we explore how algorithms have agency. We find that scientific discourse is highly situated and rarely about AI in general. It overwhelmingly charges algorithms with the capacity to solve problems and these problems are rarely about algorithms in their origin. Conversely, it rarely charges algorithms with the capacity to cause problems and when it does, other algorithms are typically charged with the capacity to solve them. Based on these findings, we argue that while a more expert-informed coverage of AI is likely to be less sensationalist and show greater attention to the specific situations where algorithms make a difference, it is unlikely to stage AI as particularly controversial. Consequently, we suggest conceptualising AI as a political situation rather than something inherently controversial.

This paper presents a cartography of the digital literacy academic field. Such cartography is comprised of two sections: a categorization of the field through literature review and analysis, and an exploration of its main issues through thematic and network analysis. On the one hand, five conceptual categories of digital literacies are found: functional, sociocultural, critical, transformative, and sociomaterial. On the other, main issues are described with 21 recurring themes of digital literacy and a few networks depicting its most salient matters of concern, concluding with an interpretation of these in the composition of 8 encompassing issue spaces: digital literacies conceptions and practices, digital literacy in education, access and digital divide, digital texts and literacy, websites and social networks, digital technologies at the workplace and healthcare, digital technologies users and uses, and information issues. Finally, a few paragraphs are dedicated to the limitations of categorizing and issue mapping.

Scholarship from the design discipline and policy sciences has produced rich empirical and theoretical knowledge on the intersection of policy and design. However, using concepts that pair “policy” and “design” in various ways, often with different meanings, can confuse practitioners and scholars alike. This confusion is further exacerbated by the sheer variety of online information, including peer-reviewed articles, books, reports, blogs, courses, and the websites of prominent scholars, practitioners, and policy actors. To address this, we analyze “Policy * Design” concepts from a Google Search Engine scraping tool and, in doing so, identify four distinct approaches: “policy design,” “design for policy,” “design in policy,” and “design policy.” The results are presented through issue mapping, and the content of these results is discussed. Finally, we suggest strategies for bridging the gap between “Policy * Design” definitions and then provide a preliminary description of these concepts.

The article builds upon critical border studies for the study of the European migration crisis that take into account the digital, both in terms of telecommunications infrastructure and media platforms. In putting forward an approach to migration studies with digital devices, here the emphasis is shifted from “bordering” to “routing.” First, the current analytical situation is sketched as one where the “connective” route is contrasted to the “securitised” one, made by European policy and monitoring software. Subsequently, we ask, how are connective migrant routes being made into accounts and issues in social media? Two case studies are presented, each describing routing in terms of the distinctive accounts made of migrant journeying. In the first, routes are seen from the point of view of its curation in Getty Images, and in particular of the images privileged by its social layer. In the image collection, the “sanitised route” (as we call it) gradually leads to a soft landing in Europe, cleansed of anti-refugee sentiment. In the second, we ask how camps and borders are problematized from the point of view of the traveler using TripAdvisor. In the “interrupted tourist route,” would-be visitors are concerned with a Europe made unsafe, thereby rerouting their own journeys on the basis of social media commenting. We conclude with reflection about the advantages of employing social media in migration and border studies for the study of “media journeys” as routes from multiple vantage points, developing the idea that route-work also can be understood as platform-work.

The aim of this study was to better identify the information generated by citizens and to explore the regional social phenomenon whereby higher quality urban services focused on understanding regional issues are promoted. Citizens voluntarily and continuously communicate with local government both online and offline. We wanted to determine how civic information can be applied to urban planning. We selected Shiheung City, Republic of Korea, as our study area, as the city is formed of various types of land use: industrial areas, agricultural land, and residential areas. This area is facing developmental pressure with released development-restricted areas, and has been environmentally damaged by industrial complexes. We conducted a semantic network analysis of the top 10% most commonly used nouns in civil complaints to determine the keywords. Each thematic map we created was based on geographical information to explain the temporary, continuous, and chronic issues. The chronic problems were discussed in relation to the regional development process. The process of identifying and analyzing local issues by analyzing information voluntarily provided by citizens plays an important role in government-led urban management planning and policy formation and can contribute to decision making in the development of future urban policies.

The potential response of shoreface depositional environments to sea level rise over the present century and beyond remains poorly understood. The shoreface is shaped by wave action across a sedimentary seabed and may aggrade or deflate depending on the balance between time-averaged wave energy and the availability and character of sediment, within the context of the inherited geological control. For embayed and accommodation-dominated coastal settings, where shoreline change is particularly sensitive to cross-shore sediment transport, whether the shoreface is a source or sink for coastal sediment during rising sea level may be a crucial determinant of future shoreline change. While simple equilibrium-based models (e.g. the Bruun Rule) are widely used in coastal risk planning practice to predict shoreline change due to sea level rise, the relevance of fundamental model assumptions to the shoreface depositional setting is often overlooked due to limited knowledge about the geomorphology of the nearshore seabed. We present high-resolution mapping of the shoreface-inner shelf in southeastern Australia from airborne lidar and vessel-based multibeam echosounder surveys, which reveals a more complex seabed than was previously known. The mapping data are used to interpret the extent, depositional character and morphodynamic state of the shoreface, by comparing the observed geomorphology to theoretical predictions from wave-driven sediment transport theory. The benefits of high-resolution seabed mapping for improving shoreline change predictions in practice are explored by comparing idealised shoreline change modelling based on our understanding of shoreface geomorphology and morphodynamics before and after the mapping exercise.

Coastal areas have traditionally been difficult locations to collect consistent, high-resolution bathymetric data via vessel-based acoustic surveys. The use of phase-measuring sidescan sonar is becoming more prevalent, particularly in shallow (< 20 m) coastal waters. Instruments used in the field over the last decade by the lead author are discussed here. This work is intended to serve as an introduction to the coastal scientist interested in the operation, use, and data sets associated with these instruments. Hydrographers unfamiliar with phase-measuring sidescan sonar will also benefit from insights regarding survey planning, data acquisition, and processing. These instruments collect co-located sidescan backscatter and swath bathymetry. The effective bathymetric swath widths can be 2 to 3 times that of multibeam echosounders making phase-measuring sidescan sonars ideal for shallow water mapping operations. These large effective swath widths offset the high levels of noise and processing needed in these bathymetric data sets relative to multibeam data. The sidescan backscatter and bathymetric data sets can be used individually, but the co-location allows for uses and analyses not feasible with other data sets. These instruments are well-suited to collect data for a suite of seafloor mapping projects and science-based investigations. Examples from a wide range of projects are detailed here for the shallow water mapping community and the multi-disciplinary groups who may benefit from the data and insights presented here.
