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)
Introduction What children learn in school forms the basis for their approach to society and to science. To foster the role of spatial information in society and to support the development of spatial skills and competences it is important to point learners early on to the transdisciplinary power of spatial information and spatial thinking.

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)
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)
With the advent of GI Science and Geographic Information in general public (for example via virtual globes and navigation systems), education systems all over the world start integrating them in their curricula including competences like spatial orientation, spatial learning, and spatial thinking. The presented Geospatial-Learning@PrimarySchool project(More)
