European legislation such as the Marine Strategy Framework Directive emphasizes the importance of protecting the marine environment. Also from an economic point of view (e.g. fisheries), the state of the oceans and coastal waters is an important influence.
The availability of comprehensive marine observation data describing the state of the oceans and coastal waters is a key factor when taking decisions that may affect the marine environment. Within this presentation we introduce the results of the European FP7 project NeXOS which has developed a complete technology stack for enabling a seamless data flow from marine sensors into INSPIRE compliant infrastructures.
The NeXOS project has addressed challenges on several layers and perspectives. This comprises, on the one hand, sensor plug-and-play on observation platforms using self-configuration mechanisms based on a common sensor metadata format (OGC SensorML) and, on the other hand, a seamless data flow between the sensors/platforms for delivering data via potentially constrained communication links to Sensor Web servers (OGC Sensor Observation Service, SOS).
During the development of the NeXOS Sensor Web architecture, attention was paid to the corresponding INSPIRE recommendations. On the one hand, the data modelling approach, which is based on the ISO/OGC Observations and Measurements (O&M) standard, considers the recommendations of the INSPIRE Technical Guidance for the use of Observations & Measurements and Sensor Web Enablement-related standards in INSPIRE. On the other hand, the Sensor Web servers providing Web based access to the collected observation data via the SOS interface are also aligned to the INSPIRE Technical Guidance for implementing download services using the OGC Sensor Observation Service and ISO 19143 Filter Encoding.
During the currently ongoing integration and demonstration activities, the benefits of this approach have become obvious. Besides the fast publication of collected data, it becomes possible to share data collected by multiple organisations in a common manner. We also show, how the INSPIRE Technical Guidance allows to abstract from specific characteristics of the different sensor platforms. For example, the INSPIRE framework provides efficient means to handle data not only from stationary platforms but also offers the support of more complex scenarios such as mobile platforms (e.g. gliders or research vessels).
As a result, the NeXOS developments illustrate how INSPIRE Technical Guidance documents can be used for achieving a highly interoperable data flow from marine sensing devices into Web-based infrastructures.
