As directories of named places, gazetteers link the names to geographic footprints and place types. Most existing gazetteers are managed strictly top-down: entries can only be added or changed by the responsible toponymic authority. The covered vocabulary is therefore often limited to an administrative view on places, using only official place names. In(More)
Touch-sensitive devices become more and more common all-around. Many people use touch interaction, especially on small devices like iPhone or other mobile phones and handhelds. But do they really understand the different gestures, know which gesture is the correct one for the intended action and do they know how to transfer the gestures to bigger devices(More)
The Linked Brazilian Amazon Rainforest Data contains observations about deforestation of rainforests and related things such as rivers, road networks, population, amount of cattle, and market prices of agricultural products. The Linked Data approach offers thus to combine ecological, economical and social dimensions together. Our aim has been to 1)(More)
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)
Fostering spatial competencies of children has been positively discussed across disciplines and institutes. As most exiting tools for spatial learning are based on existing software such as geographic information systems, these tools may not be suitable for children at the age of 8 to 12. With this goal in mind, we designed the Orientation Gaming App(More)
Exploring complex spatiotemporal data can be very challenging for non-experts. Recently, gestural interaction has emerged as a promising option, which has been successfully applied to various domains, including simple map control. In this paper, we investigate whether gestures can be used to enable non-experts to explore and understand complex(More)
Managing spatial data in paper maps is quite different from managing digital spatial information. Sometimes manual vectorization of scanned maps is the only way to produce digital cartography, especially when the only source of spatial information is a paper map. Digital scanning and manual vectorization are two processes well known for adding error to data(More)
