This paper describes the Sensor Interface Descriptor (SID) model and focuses on presenting and evaluating the SID creator, a visual approach to create instances of the SID model. Those SID instances comprise the knowledge required to integrate a sensor with the Sensor Web. This integration is done by an SID interpreter which uses an SID instance to… (More)
An important aspect of a Dutch research project into usable (and well scaled) mobile maps for consumers is presented: the development of an appropriate field-based usability evaluation methodology for the prototype of a geo-mobile application that will be the result of a user centred design approach. Automatic generalisation, required for the user's… (More)
Currently, generalization of topographic base maps is driven by the existing supply of topographic data. To provide an optimal topographic setting for thematic information layers, the topographic information displayed on the base map should satisfy the user's information needs. Therefore, we propose an approach towards a method on automated generalization… (More)
Today, exposure to new and unfamiliar environments is a necessary part of daily life. Effective communication of location-based information through location-based services has become a key concern for cartographers, geographers, human-computer interaction and professional designers alike. Recently, much attention was directed towards Augmented Reality (AR)… (More)
Augmenting the physical environment with virtual geo-referenced information is a current research theme in both the Geo-Information and Human-Computer Interaction domains. In this paper we draw from our work on augmentation of urban tourism destinations in order to identify the most important open questions, issues and challenges for the GeoHCI field.
Recent updates in Google Earth, which provide the possibility to couple cartographic animation with real-time information dissemination, make this software suitable for environmental researchers who work with spatio-temporal data and participate on distributed research projects. Even though it seems simple, computer supported group work with geospatial… (More)
