SensorML 2.0 Metadata Elements

Sensor Observation Service (SOS)

Sensor Observation Service (SOS) Operations

SOS 2.0 Core Operations

• GetCapabilities - provides access to metadata and detailed information about the operations available by an SOS server.

• DescribeSensor - enables querying of metadata about the sensors and sensor systems available by an SOS server.

• GetObservation - provides access to observations by allowing spatial, temporal and thematic filtering.

SOS 2.0 Enhanced Operations

• GetObservationByID - provides access to observations from an SOS by passing only the ID of an observation.

• GetFeatureOfInterest - provides direct access to the features of interest for which the SOS offers observations.

SOS 2.0 Transactional Operations

• InsertSensor – allows registration of new sensors at the SOS.

• DeleteSensor – allows the deletion of registered sensors and all their associated observations.

• InsertObservation – allows the insertion of observations in an SOS server.

SOS 2.0 Result Handling Operations

• InsertResult - allows the insertion of observation results in an SOS server. Before inserting, it is necessary that a template with observation metadata exists in the server.

• InsertResultTemplate - allows the insertion of an observation template, containing the observation metadata and structure of the results. This operation is necessary for later insertion of observation results.

• GetResultTemplate - provides access to a template containing the structure of results returned by later invocation of the GetResult operation.

• GetResult - provides access to an observation result without the observation metadata and without the information about the structure of the results.

GetObservation

Can be networks, platforms, sensors, etc.. Anything that can have an output

GetObservation

Depends on the procedure.

WaterML 2.0

• provide a common exchange format for hydrological time-series

• build on existing standards like GML and Observations & Measurements

• provide the option to fully store information including information regarding quality, validity/interpolation, and remarks

WaterML 2.0: Part 1- Timeseries – 2012

A sampling feature located in space A series of values in time

Sampling Features

WaterML

WaterML 2.0 - Part 2 - Ratings, Gaugings and Sections - 2016

• Conversion tables, or conversion curves, that are used for the conversion of related hydrological phenomenon.

• Gauging observations– the observations performed to develop conversion table relationships.

• Cross sections - survey observations made of the geometric structure of features, such as river channels, storages etc.

WaterML 2 – Part 3: Surface Hydrology Features (HY_Features) – Conceptual Model

In review process internally by OGC Members

How can we represent these using acommon model ?
