Human observations have the potential to significantly improve the actuality and completeness of data about phenomena such as noise distribution in urban environments. The Human Sensor Web aims at providing approaches for creating and sharing human observations as well as sensor observations on the Web. One challenge is the integration of these observations(More)
We present iPiccer, a system that allows mobile camera phones users to interact with meta-tagged image material available from web repositories, such as flickr in two novel ways. Users of the system are able to infer photo tags from their location and orientation, but are also able to infer their location and orientation from their spatial photo tags. An(More)
In this paper, we describe an approach for integrating Monte Carlo simulation in the Model Web to propagate uncertainty in model inputs and processes. In our approach, the models and model services are not capable to handle uncertainties. Therefore, we developed separate Web service components that can be used to manage uncertainties in the model workflow(More)
This paper introduces the latest state of the interoperable Sensor Web and Web Processing standards specified by the Open Geospatial Consortium. Based on these components it becomes possible to share, integrate and analyse observation data across political and administrative borders as well as across multiple thematic domains. We present the 52°North open(More)
