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)

Interoperable data exchange and reproducibility are increasingly important for modern scientific research. This paper shows how three open source projects work together to realize this: (i) the R project, providing the lingua franca for statistical analysis, (ii) the Open Geospatial Consortium's Sensor Observation Service (SOS), a standardized data… (More)
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)

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)

The Sensor Web is a collection of standards and software solutions that allows the management of and data retrieval from sensors through the internet. The Open Geospatial Consortium's (OGC) Sensor Observation Service (SOS) is the core web service to provide sensor data in an interoperable, standardized way. Because its goals are so generic, this service is… (More)

The sos4R package provides simple yet powerful access to OGC Sensor Observation Service instances. The package supports both encapsulation and abstraction from the service interface for novice users as well as powerful request building for specialists. sos4R is motivated by the idea to close the gap between the Sensor Web and tools for (geo-)statistical… (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)
