52°North Sensor Observation Service (SOS)

Master Develop OpenHUB
Master Build Status Develop Build Status OpenHUB

Description

Standardized, web-based upload and download of sensor data and sensor metadata

The 52°North Sensor Observation Service (SOS) provides an interoperable web-based interface for inserting and querying sensor data and sensor descriptions. It aggregates observations from live in-situ sensors as well as historical data sets (time series data).

The 52°North SOS is a reference implementation of the OGC Sensor Observation Service specification (version 2.0), an interoperable interface for publishing and querying sensor data and metadata. It was implemented during the OGC Web Services Testbed, Phase 9 (OWS-9) and tested to be compliant to this specification within the OGC CITE testing in December of 2012.

The 52°North SOS enables the user to:

  • insert and retrieve georeferenced observation data
  • access georeferenced measurement data in a standardized format (ISO/OGC Observation and Measurement - O&M 2.0, OGC WaterML 2.0)
  • insert and retrieve sensor descriptions (encoded according to the OGC SensorML standard - SML 1.0.1, SML 2.0)
  • publish measurement data (near real-time, as well as archived data)

An extension accommodates additional INSPIRE Directive requirements, thus ensuring interoperable exchange of any kind of observation data across political, administrative and organizational boundaries. Client applications, such as Helgoland enable analysis and visualization of the measurement data provided via the SOS server.

Features

Future

From version 5.x of the 52N SOS, the database model and the DAO layer of 52N SOS and the 52N Sensor Web REST-API would be merged to finally provide an easy-to-install and easy-to-configure service that provides the OGC SOS 2.0 interface and the 52N Sensor WEB REST-API to easily access the observed data via a restful interface.

For that the similar database models of both services would be harmonized to use the same model. Furthermore, the new database model is to be defined in this way that a simple basic database model would provide the main features of the SOS and the Sensor WEB REST-API and can be easily extended to provide further features.

The Data Access Objects (DAO) layer would also be harmonized to provide a single point for accessing and manipulating the data in the database. This would reduce the maintenance and new database features would be easier supported by the SOS and the REST interface.

In the Sensor Web Suite database project the harmonized database model and the DAO layer would be provided as a separate project that would be use in the future 52N SOS and 52N Sensor WEB REST-API implementations. Additionally the 52N SOS Proxy will also use this project to persist the metadata of the harvested SOS services.
