[Termes IGN] web des donnéesRésumé : (Auteur) This article presents SCOPED, an innovative approach for extracting environmental data using OGC services. In the field of water resource management, SCOPED-W (‘W’ for ‘Water’) is a method that was developed in the framework of EU/FP7 IASON and EOPOWER projects. This platform supports the collection of data required to build a Soil and Water Assessment Tool (SWAT) model and the uptake, spatialization and dissemination of raw data generated from the outputs of different SWAT models for the Black Sea region. Scientists are documenting the data served by the platform in ISO standardized metadata to support informed use. SCOPED-W primarily targets the community of SWAT users in the Black Sea region but it can easily be replicated in other geographical areas. Additionally, the SCOPED approach is based on data interoperability that makes it fully compatible with other domains of application as demonstrated here with three original use cases. The article also highlights the benefits of the approach for the GEO community and discusses future improvements for supporting integration with other platforms such as UNEP Live.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) We present a new viewpoint-based approach to improving the exploration effects and efficiency of trajectory datasets. Our approach integrates novel trajectory visualization techniques with algorithms for selecting optimal viewpoints to explore the generated visualization. Both the visualization and the viewpoints will be represented in the form of KML, which can be directly rendered in most of off-the-shelf GIS platforms. By playing the viewpoint sequence and directly utilizing the components of GIS platforms to explore the visualization, the overview status, detailed information, and the time variation characteristics of the trajectories can be quickly captured. A case study and a usability experiment have been conducted on an actual public transportation dataset, justifying the effectiveness of our approach. Comparing with the basic exploration approach without viewpoints, we find our approach increases the speed of information retrieval when analyzing trajectory datasets, and enhances user experiences in 3D trajectory exploration.

[Termes IGN] service web géographiqueRésumé : (Auteur) Geospatial data catalogs enable users to discover and access geographical information. Prevailing solutions are document oriented and fragment the spatial continuum of the geospatial data into independent and disconnected resources described through metadata. Due to this, the complete answer for a query may be scattered across multiple resources, making its discovery and access more difficult. This paper proposes an improved information retrieval process for geospatial data catalogs that aggregates the search results by identifying the implicit spatial/thematic relations between the metadata records of the resources. These aggregations are constructed in such a way that they match better the user query than each resource individually.

[Termes IGN] web mappingRésumé : (Auteur) Interpreting terrain in traditional 2D maps can be challenging. However, recent work has shown how interactive shearing of terrain can help users better understand topography and extract elevation information from a map. Using this approach, user input – paired with existing interactions such as pan and zoom – triggers brief ephemeral shearing animations that expose depth and shape information in terrain maps. The animations use motion to enhance the perception of depth and convey the impression of a shaking jelly model that oscillates until it comes to rest. However, it is still unclear how the parameters of these animations impact the effectiveness of the method or if the animations may have negative side effects. Moreover, it is unknown whether interactive relief shearing is accessible enough to be used in common web maps. To investigate these questions, we conducted a user study with 49 cartographers and visualization experts. These experts interactively configured shearing animations and assessed the technique’s usability and applicability. To create a platform for the user study and demonstrate that interactive shearing of terrain is technically feasible in browsers, we implemented a web map with interactive shearing animations. All experts found that interactive relief shearing made it easier to see differences in elevation on orthophoto maps. Future web maps could include shearing animations, making it easier for viewers to interpret terrain and see differences in elevation.

[Termes IGN] Triangulated Irregular NetworkRésumé : (Auteur) Virtual globes play an important role in representing three-dimensional models of the Earth. To extend the functioning of a virtual globe beyond that of a “geobrowser”, the accuracy of the geospatial data in the processing and representation should be of special concern for the scientific analysis and evaluation. In this study, we propose a method for the processing of large-scale terrain data for virtual globe visualization and analysis. The proposed method aims to construct a morphologically preserved multi-resolution triangulated irregular network (TIN) pyramid for virtual globes to accurately represent the landscape surface and simultaneously satisfy the demands of applications at different scales. By introducing cartographic principles, the TIN model in each layer is controlled with a data quality standard to formulize its level of detail generation. A point-additive algorithm is used to iteratively construct the multi-resolution TIN pyramid. The extracted landscape features are also incorporated to constrain the TIN structure, thus preserving the basic morphological shapes of the terrain surface at different levels. During the iterative construction process, the TIN in each layer is seamlessly partitioned based on a virtual node structure, and tiled with a global quadtree structure. Finally, an adaptive tessellation approach is adopted to eliminate terrain cracks in the real-time out-of-core spherical terrain rendering. The experiments undertaken in this study confirmed that the proposed method performs well in multi-resolution terrain representation, and produces high-quality underlying data that satisfy the demands of scientific analysis and evaluation.
