Cartography-oriented design of 3D geospatial information visualization – overview and techniques / Amir Semmo in Cartographic journal (the), Vol 52 n° 2 (May 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 2 (May 2015) . - pp 95 - 106 Titre : Cartography-oriented design of 3D geospatial information visualization – overview and techniques Type de document : Article/Communication Auteurs : Amir Semmo, Auteur Année de publication : 2015 Article en page(s) : pp 95 - 106 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] carte interactive [Termes IGN] conception cartographique [Termes IGN] iconographie [Termes IGN] réalité virtuelle [Termes IGN] sémiologie graphique [Termes IGN] temps réel [Termes IGN] visualisation 3D [Vedettes matières IGN] Géovisualisation Résumé : (Auteur) In economy, society and personal life map-based interactive geospatial visualization becomes a natural element of a growing number of applications and systems. The visualization of 3D geospatial information, however, raises the question how to represent the information in an effective way. Considerable research has been done in technology-driven directions in the fields of cartography and computer graphics (e.g., design principles, visualization techniques). Here, non-photorealistic rendering (NPR) represents a promising visualization category – situated between both fields – that offers a large number of degrees for the cartography-oriented visual design of complex 2D and 3D geospatial information for a given application context. Still today, however, specifications and techniques for mapping cartographic design principles to the state-of-the-art rendering pipeline of 3D computer graphics remain to be explored. This paper revisits cartographic design principles for 3D geospatial visualization and introduces an extended 3D semiotic model that complies with the general, interactive visualization pipeline. Based on this model, we propose NPR techniques to interactively synthesize cartographic renditions of basic feature types, such as terrain, water, and buildings. In particular, it includes a novel iconification concept to seamlessly interpolate between photorealistic and cartographic representations of 3D landmarks. Our work concludes with a discussion of open challenges in this field of research, including topics, such as user interaction and evaluation.

ARAMANI – Decision-support tool for selecting optimal participatory mapping method / Jiří Pánek in Cartographic journal (the), Vol 52 n° 2 (May 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 2 (May 2015) . - pp 107 - 113 Titre : ARAMANI – Decision-support tool for selecting optimal participatory mapping method Type de document : Article/Communication Auteurs : Jiří Pánek, Auteur Année de publication : 2015 Article en page(s) : pp 107 - 113 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] approche participative [Termes IGN] cartographie [Termes IGN] données localisées des bénévoles [Termes IGN] méthodologie [Termes IGN] outil d'aide à la décision Résumé : (Auteur) Participatory mapping is an emerging practice in the community development discourse. With its roots in the Participatory Rural Appraisal, it brings active involvement of the community and subjectivity of non-cartographers into the spotlight. The crucial question is how one can choose the most optimal method for participatory mapping, taking into account the specific needs and assets of the community. In this paper, the author presents the ARAMANI tool, expert knowledge-based decision support system operating with 10 participatory mapping methods and experience of 172 survey responders. ARAMANI tool allows users to describe their community assets and needs while combining them with a value-based system for deciding which method to select. The tool is designed as a user-friendly webpage with guidelines and examples of best practices for each method.

Towards better WMS maps through the use of the styled layer descriptor and cartographic conflict resolution for linear features / Ionuţ Iosifescu Enescu in Cartographic journal (the), Vol 52 n° 2 (May 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 2 (May 2015) . - pp 125 - 136 Titre : Towards better WMS maps through the use of the styled layer descriptor and cartographic conflict resolution for linear features Type de document : Article/Communication Auteurs : Ionuţ Iosifescu Enescu, Auteur ; Nadia H. Panchaud, Auteur ; Magnus Heittzler, Auteur ; et al., Auteur Année de publication : 2015 Article en page(s) : pp 125 - 136 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] analyse comparative [Termes IGN] cartographie par internet [Termes IGN] conflit d'espace [Termes IGN] généralisation cartographique automatisée [Termes IGN] objet cartographique [Termes IGN] Styled Layer Descriptor [Termes IGN] Web Map Service Résumé : (Auteur) The Open Geospatial Consortium (OGC) Web Map Service (WMS) and Styled Layer Descriptor (SLD) standards define a way of dynamically producing maps from vector data. However, this dynamic process often results in maps that are not easily readable when the underlying data are automatically represented at smaller scales than the original data were intended for. Fortunately, the SLD rules can be decoded, the symbolization rules translated into geometrical features, and cartographic conflicts detected and partially solved. The conflicting features can be identified based on the use of few basic geospatial analysis functions. After a solution that minimizes these conflicts emerges, new SLD rules are generated that attempt to visually solve the cartographic conflicts. The new SLD rules can then be applied on-demand by a cartographic proxy server that rewrites the incoming GetMap requests to use the new SLD rules. The process for improving the WMS cartographic output has several stages, grouped into preparatory steps (basic automatic generalization methods, rough scale-dependent SLD symbolization) and real-time processing steps (detection of cartographic conflicts, conflicts solution and generation of new SLD rules). The entire process of detecting and solving cartographic conflicts in the maps produced by WMS through the use of overriding SLD rules is described in detail. Furthermore, it is conceivable to transform the conflicting features into spatial objects containing methods for discovering appropriate SLD values that minimize conflicts. Such approaches can bring the performance of automatic detection and correction of cartographic conflicts above the threshold required for interactive visualization, thus, making the process of dynamically solving cartographic conflicts in WMS servers a viable solution.

Hypercube-based visualization architecture for web-based environmental geospatial information systems / Ionuţ Iosifescu Enescu in Cartographic journal (the), Vol 52 n° 2 (May 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 2 (May 2015) . - pp 137 - 148 Titre : Hypercube-based visualization architecture for web-based environmental geospatial information systems Type de document : Article/Communication Auteurs : Ionuţ Iosifescu Enescu, Auteur ; Vassilios Vescoukis, Auteur ; Cristina M. Iosifescu Enescu, Auteur ; et al., Auteur Année de publication : 2015 Article en page(s) : pp 137 - 148 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] données environnementales [Termes IGN] exploration de données [Termes IGN] géomatique web [Termes IGN] hypercube [Termes IGN] visualisation cartographique Résumé : (Auteur) The geospatial field significantly influences the development of the environmental domain, including a wide range of geospatial and cartographic information systems, such as Geographic Information Systems (GIS), Multimedia Atlas Information Systems (MAIS) and more recently web-based GIS (Web-GIS). In this context, we introduce web-based environmental geospatial information systems (Web-EGIS) as a special case of Web-GIS, aiming to integrate the functionalities of geospatial information systems with the enormous quantity of specialized, distributed and highly heterogeneous environmental geo-referenced data and services. We define three main characteristics of the Web-EGIS. The first is a generic hypercube-based data organization and visualization. The next characteristic is a standard-based, three-tier service-oriented architecture. The third and last characteristic is the traceability of the architectural and design decisions, for which we introduce the new concept of an ‘Environmental Application Context’, arguing that not only the functional but also the non-functional requirements (NFRs) have an important role in defining the architecture, software components and data services of such systems. In a nutshell, a Web-EGIS is characterized by a coherent user experience through the hypercube-based visualization concept, technically supported by a service-oriented architecture that is structured according to an extensive analysis of NFRs. On this basis, we introduce the Geodata visualization and interactive training environment (GeoVITe) Platform for Interdisciplinary Environmental Research as a reference implementation of a Web-EGIS with its basic design requirements, integrative hypercube-based visualization for heterogeneous data sources, extended web cartography functionalities, and its de facto system architecture. The concept of the hypercube-based visualization is better transferred to the system architecture by understanding the ‘Environmental Application Context’ of this particular Web-EGIS, which also makes it easier to maintain and enhance. The resulting system is a support platform for research activities in the environmental domain.

Automated generation of schematic network maps adaptive to display sizes / Peng Ti in Cartographic journal (the), Vol 52 n° 2 (May 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 2 (May 2015) . - pp 168 - 176 Titre : Automated generation of schematic network maps adaptive to display sizes Type de document : Article/Communication Auteurs : Peng Ti, Auteur ; Zhilin Li, Auteur ; Zhu Xu, Auteur Année de publication : 2015 Article en page(s) : pp 168 - 176 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] analyse de données [Termes IGN] cartographie [Termes IGN] généralisation cartographique automatisée [Termes IGN] lisibilité perceptive [Termes IGN] représentation des données [Termes IGN] réseau de transport Résumé : (Auteur) Schematic maps have been popularly used for the representation of metro (or underground) lines and nowadays have also been used for the representation of other network maps. This paper presents a strategy for automated generation of schematic network maps for different display sizes, based on a redistribution of line density. This strategy consists of three steps: (a) estimation of spatial density of the network maps, (b) automated redistribution of line density in order to improve map clarity, for different display sizes, and (c) automated generation of schematic representations. An experimental evaluation has been carried out by using two sets of real-life network data. The results indicate that this strategy is able to generate schematic maps with much improved clarity for different display sizes and well-preserved map recognition.

To this end a usability test with 18 participants has been conducted. The participants were given mapping tasks to complete using iD and observed with the thinking aloud method as well as screen recording and mouse/keyboard logging. Additionally, the test persons were interviewed after each test. The data gathered were analysed with regard to key usability criteria such as learnability, efficiency, error tolerance, and subjective user satisfaction. The outcome of this study is the identification of usability issues from which possible improvements of the tool have been derived. The study shows that iD is an overall usable tool for novice users, but still shows opportunities for improvement especially in terms of learnability and error handling.

Trajectory data of objects form a large component of this resource and even the smaller trajectory datasets are a representational challenge for cartography. We present a method that regularizes mapped trajectory data into an object × time interval matrix to better compare the direction characteristics of objects. We use a simulated annealing method to optimize the order of object rows at a specific time interval so that objects that are close together in space tend to be close together in the matrix. We also graphically represent the distance between objects and the general direction the object is travelling in the matrix, which is called Adaptive Relative Motion (ARM). Finally, we demonstrate the implementation of ARM through a case study of dolphin trajectories.

Symbolization and generalization to map water pipe data flow and water quality at different scales / Anne Ruas in Cartographic journal (the), Vol 52 n° 2 (May 2015)  

Public [article]  inCartographic journal (the) > Vol 52 n° 2 (May 2015) . - pp 149 - 158 Titre : Symbolization and generalization to map water pipe data flow and water quality at different scales Type de document : Article/Communication Auteurs : Anne Ruas , Auteur ; Ha Pham, Auteur Année de publication : 2015 Article en page(s) : pp 149 - 158 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] conception cartographique [Termes IGN] généralisation cartographique automatisée [Termes IGN] niveau de détail [Termes IGN] pollution des eaux [Termes IGN] représentation multiple [Termes IGN] réseau de distribution d'eau [Termes IGN] réseau technique souterrain [Termes IGN] visualisation cartographique [Vedettes matières IGN] Généralisation Résumé : (Auteur) Mapping drinking water flow is a real challenge not only to detect water leaks but also to control the quality of the water. In France, 900,000 km of water pipe serves 99% of the population. A recent law imposes the mapping of these pipelines on a known geographical system with a planar positional accuracy from 0.4 to 1.5 m according to the age and type of the pipeline. Wireless sensors and models based on computational fluid mechanics (CFD) allow to study flow and to reconstruct parameters such as velocity, pressure and a chemical concentration at each point. This information can be used to detect leaks and to control the concentration of chlorine or other chemical products. However, this information is not easy to map on GIS due to the small width of water pipe and the very high quantity of points necessary for data flow computation. In this research work, we propose solutions to map this information at different levels of detail with other information such as roads and buildings. We first propose to use area symbols instead of punctual symbols to improve zoom-in visual effects. We also propose to generalize initial water data for zoom-out processes. We use the axis of the water pipe as basic geometry and we segment it. We then compute a generalized value of pressure, velocity or chemical concentration for each segment with specific function adapted to the property we wish to study. We propose a conceptual data schema that describes the required information to map this data at different levels of detail. The solution has been fully implemented on experimental data and illustrated by means of a dedicated web mapping that proposes a set of GIS functions such as the selection of the data, zooming functions but also the animation to see the propagation of a chemical product in the water pipe.

We present the results of an empirical user study that aims to identify and assess the main graphical characteristics that are used by map users to recognize the design principles which constitute the topographic mapping style adopted by IGN (Institut National de l'Information Géographique et Forestière), France. Our results suggest that 91% of the participants were able to recognize an IGN-France topographic map amongst other topographic map products. We also determine which graphical characteristics play a role in the recognition of this cartographic style, either by visual memory or by visual perception, and identify the representation of relief, including contour lines and shaded relief, as one of the major graphical characteristics of the topographic mapping style of IGN-France. Moreover, the participants of our study considered the representation of touristic POI (points of interest), toponymy, typography, the main roads network, the individual buildings and the forests, to be essential for stylistic recognition.
