INSPIRE, the European Spatial Data Infrastructure, is at the core of much of our work. Our activities in this area include data modelling, data transformation, data provision and data usage, whereby we have a great deal of experience in integrating observational and measurement data, be it from human observers or from automated sensors, into an SDI.
Pertaining to observational data in INSPIRE, we take a twofold approach. On the one side, we provide support for Sensor Observation Service (SOS) implementations as described by INSPIRE Guidance documents. On the other side, we've been experimenting with the new OGC SensorThings API standard, allowing for RESTful access to JSON encoded data. Various services and viewers are available from our service page at http://service.datacove.eu/.
At present, we're doing a lot of work towards APIs in INSPIRE through the API4INSPIRE Project, where we're evaluating the potential of both the OGC SensorThings API as well as the OGC API - Features for use within INSPIRE.
