Across scales, the map levels (Fig. 1) can present large differences in terms of representation, due to cartographic generalisation. In our research project [2], we assume that adding intermediate representations between existing map levels could be one way to reduce these differences and to enable smooth transitions while zooming. Inspired by the literature (§2.b), we believe that smooth zooming requires regular and small variations of map complexity across scales. In this paper, we present our experiments assessing clutter variation in existing multi-scale maps. This study seeks to identify if clutter variations may predict the perceived variation of visual complexity in multi-scale maps. After presenting some research works connected to our experiments (§2), the following sections address our research issues and study procedure (§3), then results analysis (§4). Lastly, we discuss the relevance of clutter measures for our project and presents our future work (§5).

Empirical determination of geometric parameters for selective omission in a road network / Qi Zhou in International journal of geographical information science IJGIS, vol 30 n° 1-2 (January - February 2016)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 30 n° 1-2 (January - February 2016) . - pp 263 - 299 Titre : Empirical determination of geometric parameters for selective omission in a road network Type de document : Article/Communication Auteurs : Qi Zhou, Auteur ; Zhilin Li, Auteur Année de publication : 2016 Article en page(s) : pp 263 - 299 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] généralisation cartographique automatisée [Termes IGN] généralisation géométrique (de visualisation) [Termes IGN] Hong-Kong [Termes IGN] modèle empirique [Termes IGN] Nouvelle-Zélande [Termes IGN] réseau routier [Termes IGN] visualisation cartographique [Vedettes matières IGN] Généralisation Résumé : (auteur) Selective omission in a road network is a necessary operation for road network generalization. Most existing selective omission approaches involve one or two geometric parameters at a specific scale to determine which roads should be retained or eliminated. This study proposes an approach for determining the empirical threshold for such a parameter. The idea of the proposed approach is to first subdivide a large road network, and then to use appropriate threshold(s) obtained from one or several subdivisions to infer an appropriate threshold for the large one. A series of experiments was carried out to validate the proposed approach. Specifically, the road network data for New Zealand and Hong Kong at different scales (ranging from 1:50,000 to 1:250,000) were used as the experimental data, and subdivided according to different modes (i.e. administrative boundary data, a regular grid of different sizes, different update years, and different road network patterns). Not only geometric parameters, but also structural and hybrid parameters of existing selective omission approaches were involved in the testing. The experimental results show that although the most appropriate thresholds obtained from different subdivisions are not always the same, in most cases, the appropriate threshold ranges often overlap, especially for geometric parameters, and they also overlap with those obtained from the large road network data. This finding is consistent with the use of different subdivision modes, which verifies the effectiveness of the proposed approach. Several issues involving the use of the proposed approach are also addressed.

Conceptualising the geographic world: the dimensions of negotiation in crowdsourced cartography / Andrea Ballatore in International journal of geographical information science IJGIS, vol 29 n° 12 (December 2015)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 29 n° 12 (December 2015) . - pp 2310 - 2327 Titre : Conceptualising the geographic world: the dimensions of negotiation in crowdsourced cartography Type de document : Article/Communication Auteurs : Andrea Ballatore, Auteur ; Peter Mooney, Auteur Année de publication : 2015 Article en page(s) : pp 2310 - 2327 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] conception cartographique [Termes IGN] définition [Termes IGN] langage cartographique [Termes IGN] modèle sémantique de données [Termes IGN] ontologie [Termes IGN] OpenStreetMap [Termes IGN] site wiki [Termes IGN] style cartographique [Termes IGN] visualisation cartographique [Termes IGN] visualisation de données Résumé : (Auteur)In crowdsourced cartographic projects, mappers coordinate their efforts through online tools to produce digital geospatial artefacts, such as maps and gazetteers, which were once the exclusive territory of professional surveyors and cartographers. In order to produce meaningful and coherent data, contributors need to negotiate a shared conceptualisation that defines the domain concepts, such as road, building, train station, forest and lake, enabling the communication of geographic knowledge. Considering the OpenStreetMap Wiki website as a case study, this article investigates the nature of this negotiation, driven by a small group of mappers in a context of high contribution inequality. Despite the apparent consensus on the conceptualisation, the negotiation keeps unfolding in a tension between alternative representations, which are often incommensurable, i.e., hard to integrate and reconcile. In this study, we identify six complementary dimensions of incommensurability that recur in the negotiation: (1) ontology, (2) cartography, (3) culture and language, (4) lexical definitions, (5) granularity, and (6) semantic overload and duplication.

Using integrated visualization techniques to investigate associations between cardiovascular health outcomes and residential migration in Auckland, New Zealand / Jinfeng Zhao in Cartography and Geographic Information Science, Vol 42 n° 5 (November 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 5 (November 2015) . - pp 381 - 397 Titre : Using integrated visualization techniques to investigate associations between cardiovascular health outcomes and residential migration in Auckland, New Zealand Type de document : Article/Communication Auteurs : Jinfeng Zhao, Auteur ; Daniel Exeter, Auteur ; Grant Hanham, Auteur ; et al., Auteur Année de publication : 2015 Article en page(s) : pp 381 - 397 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] analyse de données [Termes IGN] analyse multicritère [Termes IGN] cartogramme [Termes IGN] migration humaine [Termes IGN] Nouvelle-Zélande [Termes IGN] santé [Termes IGN] visualisation cartographique Résumé : (Auteur) The negative health effects of living in a deprived neighborhood may influence the incidence of cardiovascular disease (CVD), even after controlling for sociodemographic characteristics, and there is evidence that residential mobility is associated with mortality and morbidity rates. However, few studies have investigated the application of integrated visualization techniques and statistic modeling to communicate the association between residential mobility and cardiovascular outcomes. We focus on examining the association between cardiovascular health outcomes and patient migration in Auckland, New Zealand, in two ways. First, we assess the association between all-cause mortality among patients with CVD and deprivation mobility, controlling for age, gender and ethnicity using multiple logistic regression at the individual level, and then visualize the results. Second, we identify aggregated geographical patterns of prevalence of CVD stratified using migration status, area-deprivation, ethnicity, and geographical area using kriskograms, ring-cartograms, and ringmaps to visualize the results. We reveal distinct patterns for purposefully selected subgroups and highlight disparities by geographic area, deprivation, and ethnicity before discussing the implications of our findings in relation to migration and health outcomes.

SketchUp as a construction tool for large-scale subsurface structures: three-dimensional visualization of the Parry Sound Domain, Grenville Province, Ontario / Jacob W.D. Strong in Cartographica, vol 50 n° 3 (Fall 2015)

In this article, the geological structure of the Parry Sound Domain is visualized using SketchUp, with geological control from a regional gravity survey, Lithoprobe seismic transects line 30 and 31, and surface geological boundaries. The multilobed structure of the Parry Sound Domain is part of a tectonic outlier that lies on top of an orogenic thrust stack. Each of the three lobes exhibits a steeper-dipping west side to depth and a shallowly dipping east side to depth. Prior interpretations of the Parry Sound Domain's subsurface structure are modified on the grounds of a multi-disciplinary approach. Three-dimensional visualization of the Parry Sound Domain will improve the current understanding of the subsurface structure in the south-western Grenville Province.
