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

2. SISS Workshop: Sensor Observation Service (SOS) | Florence Tan 2 | Outline What is Sensor Observation Service (SOS) ? Observations & Measurements (O&M) Model Overview SOS 2.0.0 Model Overview SISSsosv0.1 Overview Publishing Observational Data via SISSsosv0.1

3. 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 29-11-2012

6. SISS Workshop: Sensor Observation Service (SOS) | Florence Tan 6 | SISSsosv0.1 Overview Based on 52°North Exchangeable Encodings for SOS –based on 52°North SOS v3.5 trunk –implemented SOS 1.0.0 specification –implemented part of SOS 2.0.0 spefication: –complete core profile (GetCapabilities, DescribeSensor and GetObservation) –enhanced extension (GetFeatureOfInterest) Bundled with CSIRO Customised WaterML2.0 Domain Range Encoder –replaced the default WaterML2.0 Time Value Pair encoder Current version is in the incubation period –not included in latest release of “SISS in a Box” –performance issue with big datasets
