[Vedettes matières IGN] GéovisualisationRésumé : (auteur) We introduce a semantically-enriched method of generating color schemes for various types of digital maps that reduces the energy consumption of the display device while preserving the quality of the original design. Energy-aware design intersects two important trends in cartography. First, as more maps are viewed today on mobile, battery life has become a central constraint influencing design. Second, there is increasing need for green computing, which encourages the efficient use of energy to limit environmental impacts. This paper focuses on one important aspect of energy-aware cartography: color design. Existing research on energy-aware color adjustment methods apply broadly to images or websites. However, the colors used in maps have more structured semantic relationships than most documents viewed on mobile devices, and efforts to account for these relationships while reducing energy consumption are limited. To fill this gap, we mathematically formalize energy-aware map-color adjustment as a constrained optimization problem: we define energy consumption as the objective function and model the preservation of semantic relationships as the search constraints. We evaluate our proposed method against a common color dimming method using four maps with different semantic relationships. The evaluation suggests that our proposed method better preserves the original color semantics.

Format : 15 x 21 cm ISBN/ISSN/EAN : 978-92-1-002441-9 Langues : Français (fre) Index. décimale : 39.00 Cartographie - généralités - Cartologie Résumé : (auteur) This is a joint publication by the United Nations and the International Cartographic Association on how cartography can help to better understand, share and communicate the status of the Sustainable Development Goals (SDGS). It demonstrates how effective mapping techniques can reduce complexity to reveal relevant spatio-temporal patterns, including global population growth, socioeconomic disparities, and climate change. Such visualisations make tangible the challenges to and successes in achieving the SDGs, facilitating public awareness thereof. The publication describes foundational design decisions in cartography, introduces the SDGs in relation to geographic datasets, alongside the common map types and diagrams for representing SDG indicators, and discusses consideration for map use environments. By integrating geospatial and statistical data of the Global SDG Indicators Database, cartography can enhance action and decision-making at the local and national level and help create a sustainable world.

[Termes IGN] rédaction cartographiqueRésumé : (éditeur) The book comprises four sections. Section 1 introduces the SDGs and their relation to geospatial data, describing SDG indicators and data transformations for mapping. Section 2 describes foundational design decisions in the cartographic workflow including projections, scale, generalization, symbolization, typography, and visual hierarchy among others. Section 3 introduces common map types (e.g., choropleth maps, proportional symbol maps, dasymetric maps, bivariate maps, cartograms) and diagrams (e.g., bar charts, scatterplots, timelines) for representing the SDG indicators. Finally, Section 4 discusses considerations for map use environments such as audiences, user interfaces and interaction operators, mobile and web media, storytelling versus exploration, and open access.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) In this article, we explore the potential of wireframe design and evaluation for interactive and web-based mapping through a case study on water level visualization. Specifically, our research informed design and development of the National Oceanic & Atmospheric Administration’s (NOAA) Lake Level Viewer (http://coast.noaa.gov/llv/), an interactive and web-based geovisualization application for the Great Lakes region of North America. As part of our overall user-centered design process, we created two sets of wireframes to evaluate two aspects of the user experience: high-fidelity wireframes to illustrate the proposed representation solution using real data and low-fidelity wireframes to provide a rough sketch of the proposed interaction solution. Eighteen target users completed cognitive walkthroughs of the wireframes, with the sessions audio-recorded for subsequent transcription and qualitative data analysis. The wireframe evaluations led to a series of revisions to the functional scope and visual design of the Lake Level Viewer. The process also generated recommendations for designing water level visualizations supporting adaptive management in response to climate change as well as for leveraging wireframes in support of large-scale mapping and GIS projects.

[Vedettes matières IGN] GéovisualisationRésumé : (Auteur) The possibility of digital interactivity requires us to reenvision the map reader as the map user, and to address the perceptual, cognitive, cultural, and practical considerations that influence the user’s experience with interactive maps and visualizations. In this article, we present an agenda for empirical research on this user and the interactive designs he or she employs. The research agenda is a result of a multi-stage discussion among international scholars facilitated by the International Cartographic Association that included an early round of position papers and two subsequent workshops to narrow into pressing themes and important research opportunities. The focus of our discussion is epistemological and reflects the wide interdisciplinary influences on user studies in cartography. The opportunities are presented as imperatives that cross basic research and user-centered design studies, and identify practical impediments to empirical research, emerging interdisciplinary recommendations to improve user studies, and key research needs specific to the study of interactive maps and visualizations.
