The effectiveness of such applications is, at present, severely limited by the often poor quality of semantic annotation of the 3D models. In this paper, we show how freely available sources of georeferenced Web 2.0 information can be used for automated enrichment of 3D city models. Point referenced names of prominent buildings and landmarks mined from Wikipedia articles and from the OpenStreetMaps digital map and Geonames gazetteer have been matched to the 2D ground plan geometry of a 3D city model. In order to address the ambiguities that arise in the associations between these sources and the city model, we present procedures to merge potentially related buildings and implement fuzzy matching between reference points and building polygons. An experimental evaluation demonstrates the effectiveness of the presented methods.

A less-is-more approach to geovisualization: enhancing knowledge construction across multidisciplinary teams / C. Jones in International journal of geographical information science IJGIS, vol 23 n° 7-8 (july 2009)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 23 n° 7-8 (july 2009) . - pp 1077 - 1093 Titre : A less-is-more approach to geovisualization: enhancing knowledge construction across multidisciplinary teams Type de document : Article/Communication Auteurs : C. Jones, Auteur ; Muki M. Haklay, Auteur ; S. Griffiths, Auteur ; L. Vaughan, Auteur Année de publication : 2009 Article en page(s) : pp 1077 - 1093 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] convivialité [Termes IGN] données localisées [Termes IGN] interface utilisateur [Termes IGN] utilisateur [Termes IGN] visualisation de données Résumé : (Auteur) The 'less-is-more' concept in interface design for computer applications has recently gained ground. In this article, the concept is adopted for a user-centered design of geovisualization application. The premise is that using simple and clear design can lead to successful applications with improved ease of use. Over the last three decades, the development of GIS and geovisualization has seen a marked increase in the levels of interaction between the user, the system and the information. However, these enthusiastic advances in technology have not resulted in a significant increase in the number of users. This article suggests that types of user interaction should not simply emphasize traditional GIS functions such as zooming and panning but move towards interaction based on facilitating the knowledge construction process. Considerations are made for the complexity of the system, the task at hand and the skills and limitations of the users. These elements are particularly important when maps act as the mediators in collaboration with users across disciplinary backgrounds. In such cases, the emphasis on simplicity and usability becomes as important as functionality. In these situations a geovisualization application designed for specific uses can maximize effective development of geographic knowledge. In this article, a minimalistic design approach to geovisualization is adopted by creating a geographic profiling tool which shifts the emphasis from technological advances or interaction with the map to the interaction elements key to building the spatial knowledge of GIS experts and non-experts alike. To evaluate this notion of 'less-is-more geovisualization' the profiling tool is evaluated according to usability matrices: efficiency, effectiveness and learnability. How well the Suburban Profiler contributes to these elements is assessed by conducting a video analysis of the types and forms of user interaction available. The video analysis demonstrates the usefulness and usability of the Suburban Profiler, providing proof of concept for 'less-is-more geovisualization'.

Effects of topography on radiance from upland vegetation in north Wales / A.G. Thomson in International Journal of Remote Sensing IJRS, vol 11 n° 5 (May 1990)

The three semi-natural vegetation types examined responded differently to variations in slope and aspect. Short-cropped Agrostis grassland was the most uniform type ; and it reflected radiation in a solar-orientated diffuse manner. Variations in radiance detected from two rougher vegetation types suggested environmentally induced heterogeneity within the vegetation cover, related to aspect (Nardus grassland) or slope (Calluna heathland). The difference between reflected red and green light is proposed as a crude measure of photosynthesis that can discriminate between broad vegetation categories in undulating terrain.
