Geoprocessing services are currently a hot topic in research and industry for enabling the dynamic generation of web-based geoinformation in Spatial Data Infrastructures. An overview and an in-depth analysis of this new approach are missing yet. However, they are necessary to support upcoming projects and to streamline research towards fully web-based(More)
The Sensor Web Enablement (SWE) initiative of the Open Geospatial Consortium (OGC) defines standards for Web Service interfaces and data encodings usable as building blocks to implement a Sensor Web for geospatial applications. These standards encapsulate heterogeneous sensors installed in existing sensor networks for web-based discovery, scheduling and(More)
Cloud Computing is one of the latest hypes in the mainstream IT world. In this context, Spatial Data Infrastructures (SDIs) have not been considered yet. This paper reviews this novel technology and identifies the paradigm behind it with regard to SDIs. Concepts of SDIs are analyzed in respect to common gaps which can be solved by Cloud Computing(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)
Enabling the integration of information provided by OGC Web Processing Services into geospatial mass-market applications is promising, as it increases the availability of information for most ordinary users. This information will be most likely based on the latest available data (e.g. collected by sensors) and can thereby support the user in(More)
Classification of generalization operators is one of the challenges in current generalization research in order to provide generalization functionality meaningfully on the web. This paper proposes a classification framework for these operators by integrating the commonly accepted generalization model of Gruenreich with generic geo-data models (ISO 19109 &(More)
