“…However, we imagine that future developments will integrate processing capabilities for actual data values. For example users could task web processing services (Foerster, Schaeffer, Baranski, & Brauner, 2011), to deduce, or more specifically interpolate, data with a higher spatio-temporal coverage for the user's context such as developed in the INTAMAP project (Pebesma, Cornford, Dubois, et al, 2010).…”

Abstract. 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 discovering data and services in the Sensor Web through mobile applications. The approach is demonstrated by an air quality scenario and is implemented based on Free and Open Source Software.

“…A key concept in SOA is the orchestration of web services (WS) that has been adopted for SDIs. The application of orchestration is especially useful in SDIs since calculations are typically long running and data intensive-and therefore more suitable for remote processing [2].…”

Web service (WS) orchestration can be considered as a fundamental concept in service-oriented architectures (SOA), as well as in spatial data infrastructures (SDI). In recent years in SOA, advanced solutions were developed, such as realizing orchestrated web services on the basis of already existing more fine-granular web services by using standardized notations and existing orchestration engines. Even if the concepts can be mapped to the field of SDI, on a conceptual level the implementations target different goals. As a specialized form of a common web service, an Open Geospatial Consortium (OGC) web service (OWS) is optimized for a specific purpose. On the technological level, web services depend on standards like the Web Service Description Language (WSDL) or the Simple Object Access Protocol (SOAP). However OWS are different. Consequently, a new concept for OWS orchestration is needed that works on the interface provided by OWS. Such a concept is presented in this work. The major component is an orchestration engine integrated in a Web Processing Service (WPS) server that uses a domain specific language (DSL) for workflow description. The developed concept is the base for the realization of new functionality, such as workflow testing, and workflow optimization.

“…The existing specifications provide a baseline for GII such as for INSPIRE; these include for instance the OGC Catalogue Service (CS-W) (Nebert and Whiteside, 2004) and the more recent interfaces of the Sensor Web Enablement initiative (SWE 1 ). Other specifications such as the OGC Web Processing Service (WPS) (Schut, 2007) provide an interface for offering processing functionality as distributed Web services (Foerster et al, 2011). The publication service, described in this work, utilizes those standards to publish data in standards-based services, to increase data interoperability.…”

To improve environmental monitoring, the availability of great coverage of spatiotemporal data in an interoperable way is crucial for its integration into environmental models, for example, to compute fire danger models. To produce up-to-date and accurate results those models need the availability of data with high temporal and spatial resolution. Thus, it is promising to consider the increasing number of in-situ sensors providing observations of our environment in real-time. Today, interoperable access to such spatio-temporal data is achieved by Geospatial Information Infrastructures (GIIs). From a technical point of view GIIs provide this data through standards-based Web service interfaces. While those Web service interfaces already enable the interoperable discovery and retrieval of sensor observations, the functionality to publish sensor observations is still an arduous task. Hence, in this paper, we present an approach to improve the registration of sensors and the publication of their observations via standards-based Web service interfaces. We evaluate our approach by extending a standards-based GII and by applying the developed approach to the example of integrating in-situ weather observations into the European Forest Fire Information System for assessing fire danger in Spain.
