After two years of hard work, the Sensor Web community is pleased to announce the 52°North SOS 4.0.0 Final Release ! This release benefits from experience gained over the past few years and implements improvements and features requested by SOS operators and users.
The Sensor Web community has published a new beta release – “RC1″– of 52°North’s implementation of the OGC SOS 2.0 standard. The new SOS 4.0.0 contains improved components and new functionality. more >
We are pleased to announce that the 52 ° North SOS 4.0.0 implementation supports two new features: the SOS 2.0 Spatial Filtering Profile and the support for the optional validTime parameter in DescribeSensor requests. Both features will facilitate the modelling, storage and retrieval of mobile sensor data from SOS.
Spatial Filtering Profile
The Spatial Filtering Profile is specified in clause 12 of the SOS 2.0 specification (OGC 12-006). This profile restricts observations to spatial observations which provide a well-defined parameter for the observation location. This parameter carries the sampling geometry of the observation which represents the spatial extent where the observation result applies to and can be targeted by spatial filters. The “Spatial Observation” is defined in the Observation & Measurement 2.0 specification (OGC 10-025) subclause 7.13 and can contain any gml:AbstractGeometry type, such as points, lines or polygons.
