The OWS-4 Testbed

contributed to the maturing implementation and testing of SWE components to support the adoption of SWE at the level of Version 1.0.
In OWS-4 the Sensor Web subtask focused on maturing the existing set of SWE work items to enable the federation of sensors, platforms and management infrastructure into a
single sensor enterprise. This enterprise was envisioned to enable the discovery and tasking of sensors as well as the delivery of sensor measurements regardless of sensor
type and controlling organization. The ultimate vision was of a sensor market place where users can identify, evaluate, select and request a sensor collection regardless of
sensor type, platform or owner.
An objective in this testbed was to illustrate discovery, access to and fusing of disparate sensors Figure 19. The figure shows the Space Time Toolkit client accessing
observations from several distributed services using OGC service interfaces:
SOS – in-situ radiation sensors SOS – Doppler Radar
SOS – Lagrangian plume model

focused on integrating the SWE interfaces and encodings into workflows to demonstrate the ability of SWE specifications to support operational needs.
Emphasis for SWE during OWS-5 was on: IEEE1451 Sensor Integration
