Smooth transformations between generalized 3D building models for visualization purposes / Martin Kada in Cartography and Geographic Information Science, Vol 42 n° 4 (September 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 4 (September 2015) . - pp 306 - 314 Titre : Smooth transformations between generalized 3D building models for visualization purposes Type de document : Article/Communication Auteurs : Martin Kada, Auteur ; Andreas Wichmann, Auteur ; Tobias Hermes, Auteur Année de publication : 2015 Article en page(s) : pp 306 - 314 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications photogrammétriques [Termes IGN] Bâti-3D [Termes IGN] généralisation sémantique [Termes IGN] visualisation 3D Résumé : (Auteur) The generation of highly detailed 3D city models has significantly matured over the last couple of years. Especially for visualization purposes, these models are needed at several levels of detail (LOD) in fine granular steps that also allow for a smooth transformation from one level to the next to avoid pop-up artifacts. Several methods have been proposed for the automatic generalization of 3D building models that simplify the geometry of given boundary-based models at discrete LODs. In this paper, we present an approach to generate a transformation sequence between two discrete LODs with the purpose to later build a continuous LOD sequence. The method is based on mesh simplification techniques that are extended to a restricted use of edge collapse and vertex move operations applied on triangle meshes augmented by additional breaking lines. The validity of the approach is demonstrated on a case study that is close to reality.

Mapping and assessing coastal resilience in the Caribbean region / Nina S.N. Lam in Cartography and Geographic Information Science, Vol 42 n° 4 (September 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 4 (September 2015) . - pp 315 - 322 Titre : Mapping and assessing coastal resilience in the Caribbean region Type de document : Article/Communication Auteurs : Nina S.N. Lam, Auteur ; Yi Qiang, Auteur ; Helbert Arenas, Auteur ; et al., Auteur Année de publication : 2015 Article en page(s) : pp 315 - 322 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] Caraïbes [Termes IGN] cyclone [Termes IGN] estimation statistique [Termes IGN] outil d'aide à la décision [Termes IGN] représentation cartographique [Termes IGN] résilience écologique [Termes IGN] risque naturel [Termes IGN] surveillance du littoral [Termes IGN] système d'information géographique [Termes IGN] tempête [Termes IGN] vulnérabilité Résumé : (Auteur) Assessing the vulnerability and resilience to coastal hazards is a critical worldwide issue, especially for hurricane-prone coastal regions such as the Caribbean. However, the development of a useful metric for vulnerability and resilience assessment has a lot of challenges. Cartography and GIS analysis can contribute effectively to the solution of the issue by integrating natural and human data layers for assessment, mapping, and visualization. This paper uses the new Resilience Inference Measurement (RIM) model to assess the resilience of 25 countries in the Caribbean region to hurricanes. The RIM indices of the countries were computed using three variables representing three dimensions: exposure, damage, and recovery, and eight variables representing social-environmental capacity. The RIM resilience indices were mapped and compared with the vulnerability indices computed in a previous study. The results show that Turks & Caicos Islands had the highest resilience, whereas Montserrat had the lowest. This paper contributes to the hazard literature by demonstrating new vulnerability and resilience assessment methodologies that include validation and enable inference. The paper also contributes to the cartography and GIS literature by demonstrating the need to integrate data and perspectives from multiple disciplines and regions, as well as the ability of geospatial technology, in producing useful decision-making tools for a very pressing societal problem.

Exploring alternative map products to enhance transportation option awareness / Jessica V. Fayne in Cartography and Geographic Information Science, Vol 42 n° 4 (September 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 4 (September 2015) . - pp 345 - 357 Titre : Exploring alternative map products to enhance transportation option awareness Type de document : Article/Communication Auteurs : Jessica V. Fayne, Auteur ; Sven Fuhrmann, Auteur ; Matthew T. Rice, Auteur ; Rebecca M. Rice, Auteur Année de publication : 2015 Article en page(s) : pp 345 - 357 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] accessibilité [Termes IGN] carte thématique [Termes IGN] cartographie des flux [Termes IGN] gestion de trafic [Termes IGN] trafic routier [Termes IGN] transport public Résumé : (Auteur) The steady increase in automotive vehicle usage in highly populated areas, leading to intensified traffic, suggests the need for new approaches to traffic management and commuting options. Maps as communication products might hold one key to unlocking guided alternative mode choices as standalone products and as service components. However, traditional paper and web-based maps might lack properties and affordances that will guide users to consider alternative commuting opportunities. Through careful determination of content, use and media, our research group assesses the emotional, visual and tactile properties of map affordances to create novel transportation maps. With future user testing and modification, transportation map alternatives could enable and encourage commuters to explore transportation alternatives and select a mode of transportation that is suitable for the changing landscape in commuting and mass transportation.

Geodesign in parametric modeling of urban landscape / Ana clara Mourão Moura in Cartography and Geographic Information Science, Vol 42 n° 4 (September 2015)  

Public [article]  inCartography and Geographic Information Science > Vol 42 n° 4 (September 2015) . - pp 323 - 332 Titre : Geodesign in parametric modeling of urban landscape Type de document : Article/Communication Auteurs : Ana clara Mourão Moura, Auteur Année de publication : 2015 Article en page(s) : pp 323 - 332 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] ArcGIS [Termes IGN] Brésil [Termes IGN] GeoDesign [Termes IGN] modèle numérique du bâti [Termes IGN] paysage urbain [Termes IGN] représentation cartographique 3D Résumé : (Auteur) Parametric Modeling simulates the results of urban parameters (variables and their values) in the volumetric landscape of a city. Dynamic cartographic representation permits exploration of the impacts of current conditions defined by law and also of potential changes in these parameters. This study adopted the framework of Geodesign, as a land-use planning strategy, applying descriptive and performance models, through steps of characterization, analysis, evaluation, simulation and decision-making. This paper presents a case study of an important modernist area in Brazil, planned by Oscar Niemeyer. The main tools used were CityEngine and ArcGIS software. The result visualizes the future of urban landscape in Pampulha, considering current urban parameters, and predictive studies about the possible transformations in the area.
