Many sensor networks have been deployed to monitor Earth's environment, and more will follow in the future. Environmental sensors have improved continuously by becoming smaller, cheaper, and more intelligent. Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not(More)
Environmental sensors have continuously improved by becoming smaller, cheaper, and more intelligent over the past years. As consequence of these technological advancements, sensors are increasingly deployed to monitor our environment. The large variety of available sensor types with often incompatible protocols complicates the integration of sensors into(More)
Applications of the Web of Things reach from smart shoes posting your running performance online, over the localization of goods in the production chain, to computing the insurance cost of cars based on the actually driven kilometers. Thereby, Web of Things applications follow the REST paradigm, i.e. access to things and their properties is offered via REST(More)
The vision of a Digital Earth calls for more dynamic information systems, new sources of information, and stronger capabilities for their integration. Sensor networks have been identified as a major information source for the Digital Earth, while Semantic Web technologies have been proposed to facilitate integration.. So far, sensor data is stored and(More)
The importance of near real-time access to environmental data has steadily increased over the last years. In this article, the European Environment Agency (EEA), which receives environmental data from a large number of providers, is in focus. The heterogeneous data formats and data transfer mechanisms make the data collection and integration a difficult(More)
Building on abstract reference models, the Open Geospatial Consortium (OGC) has established standards for storing, discovering, and processing geographical information. These standards act as basis for the implementation of specific services and Spatial Data Infrastructures (SDI). Research on geo-semantics plays an increasing role to support complex queries(More)
In recent years, the standards of OGC's Sensor Web Enablement (SWE) initiative have been applied in a multitude of projects to encapsulate heterogeneous geosensors for web-based discovery, tasking and access. Currently, SWE services and the different types of geosensors are integrated manually due to a conceptual gap between these two layers. Pair-wise(More)
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)
