Sensor Observation Service (SOS) WATER FOR A HEALTHY COUNTRY FLAGSHIP SISS Workshop v2.3 Florence Tan | Research Projects Officer 8 May 2013

SISS Workshop: Sensor Observation Service (SOS) | Florence Tan 2 | Outline What is Sensor Observation Service (SOS) ? Observations & Measurements (O&M) Model Overview SOS Model Overview SISSsosv0.1 Overview Publishing Observational Data via SISSsosv0.1

SISS Workshop: Sensor Observation Service (SOS) | Florence Tan 3 | What is Sensor Observation Service (SOS) ? Interoperable web-based interface to retrieve metadata and observations from heterogeneous sensor systems, e.g. –in-situ sensors (e.g. river gauges) –moving sensor platforms (e.g. satellites) or –networks of static sensors (e.g. seismic arrays) SOS 2.0 used in conjunction with other OGC specifications, e.g. –O&M 2.0 –SensorML –SWE Common 2.0 –SWE Service Common 2.0 –WaterML 2.0 Version 2.0 adopted as OGC Standard on
