Semantically-Enabled Sensor Plug & Play for the Sensor Web
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)
Discovering the Sensor Web through Mobile Applications
Sensor data is crucial for mobile applications to support the user in the field. Several mobile applications are available for accessing such sensor data. However, a comprehensive approach for discovering such sensor data in the Sensor Web according to the user's context (i.e. the location) has not been proposed yet. This article describes an approach for… (More)
Spatial Statistics on the Geospatial Web
The Geospatial Web comprises standards and software for a wide variety of applications, ranging from typical GIS (geographic information systems) functionality, via emergency management and monitoring use cases to distributed workflows [27]. Functions include data access and visualization, but also workflows are published as web-accessible resources. Web… (More)
Reproducibility and Practical Adoption of GEOBIA with Open-Source Software in Docker Containers
Geographic Object-Based Image Analysis (GEOBIA) mostly uses proprietary software, but the interest in Free and Open-Source Software (FOSS) for GEOBIA is growing. This interest stems not only from cost savings, but also from benefits concerning reproducibility and collaboration. Technical challenges hamper practical reproducibility, especially when multiple… (More)
Sensor web and web processing standards for crisis management
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)
