“…Besides, textual languages translate spatial relationships into a non-spatial representation that can prevent an intuitive composition of the query. Alternative textual approaches based on the use of the natural language are appealing, but are characterized by verbosity and imprecision [2]. Visual languages represent an opportunity for bridging the gap between the query composition and the domain of interest, coping with the usability problems that characterize textual query languages.…”

This work proposes a visual interface for querying sets of 3D worlds for the web, designed by different authors and annotated with both ontological top-down and social bottom-up styles. The goal is to overcome the current situation where most of these worlds are like independent islands that can be accessed only using the modalities that have been designed by their authors. Usually these worlds can't be searched, because there is no high level information associated to the 3D entities that compose them. Our proposal is based on a specification, a software architecture and a set of interfaces that permit a full exploitation of the geometric and textual information contained inside these 3D environments. The applications can be different, from the retrieval of single entities for localization purposes by end users to the retrieval of complex spatial patterns for functional or typological analyses by domain experts. A case study related to cultural heritage is presented

6In this paper we present a new web mashup system for helping people and currently available on the web that can be useful for emergency purposes 13 and range from messages on forums and blogs to georeferenced photos. We 14 present here a system that, by mixing information available on the web, is 15 able to help both people and emergency professionals in rapidly obtaining 16 data on emergency situations by using multiple web channels. In this paper 17 we introduce a visual system, providing a combination of tools that demon-

“…This paper aims at examining the use of maps and graphics to support the discovery of geospatial resources in an SDI. The use of maps or geo‐referenced visualizations (as implemented for example in the Alexandria Project (Ancona et al 2002)) or spatialization is a suitable approach to improve the usability of geospatial (and non‐geospatial) content searches (Fabrikant 2000, Aufare and Trepied 2001). In this regard, most existing geoportals only provide limited tools to explore their contents with the use of graphics and maps.…”

Search interfaces for data discovery are essential in the context of a Geospatial Data Infrastructure. This paper discusses the development of a search interface, aimed at effective searches and an integration of a catalogue function and thematic mapping. For this purpose, the Resources Description Framework (RDF) is used to store the summaries of metadata of geospatial contents. These summaries are indexed based on their topics. Their topic categories are expressed using the RDF schema. The RDF queries and the transformation of results play a prominent role in the visualization of search results as a table, a thumbnail, and a bull's‐eye display with possibilities to project footprints of results on top of a basic map and thematic layers. To highlight their matches to the search terms, the Hausdorff distance and the closeness degree were applied respectively to determine the geographic and thematic relevance. Feedback from participants testing the prototype indicated the benefits of the table and thumbnail displays as well as the possibility to combine these displays with metadata and thematic mapping for data discovery. The feedback also confirmed some design challenges in the depictions of relevance and symbolization of metadata.
