Basic Desires Quickly discover sensors and sensor data (secure or public) that can meet my needs – location, observables, quality, ability to task Obtain sensor information in a standard encoding that is understandable by me and my software Readily access sensor observations in a common manner, and in a form specific to my needs Task sensors, when possible, to meet my specific needs Subscribe to and receive alerts when a sensor measures a particular phenomenon

SWE Specifications Information Models and Schema Web Services Sensor Model Language (SensorML) for In-situ and Remote Sensors - Core models and schema for observation processes: support for sensor components, georegistration, response models, post measurement processing Observations and Measurements (O&M) – Core models and schema for observations TransducerML – adds system integration and multiplex streaming clusters of observations Web Services Sensor Observation Service - Access Observations for a sensor or sensor constellation, and optionally, the associated sensor and platform data Sensor Alert Service – Subscribe to alerts based upon sensor observations Sensor Planning Service – Request collection feasibility and task sensor system for desired observations Web Notification Service –Manage message dialogue between client and Web service(s) for long duration (asynchronous) processes Sensor Registries – Discover sensors and sensor observations

More on SensorML Importance: Discovery of sensors and processes / plug-n-play sensors – SensorML is the means by which sensors and processes make themselves and their capabilities known; describes inputs, outputs and taskable parameters Observation lineage – SensorML provides history of measurement and processing of observations; supports quality knowledge of observations On-demand processing – SensorML supports on-demand derivation of higher-level information (e.g. geolocation or products) without a priori knowledge of the sensor system Intelligent, autonomous sensor network – SensorML enables the development of taskable, adaptable sensor networks, and enables higher-level problem solving anticipated from the Semantic Web

SWE Resources for Discovery Dictionaries: Phenomena Units of Measure Features of Interest SWE Registry Service Observation Offerings Sensor Types Another important function of catalog service is the registry capability to store SWE Dictionaries: Phenomena – Sensor observables are rigorously defined UOM – Units of Measure also rigorously defined and connected to the corresponding observable Sensor Types – Allows classification and further discovery of sensors by type (scanners, radars, frame cameras, in-situ, etc…) Applications – Allows classification and discovery of sensors by application (weather, spatial, traffic control, etc…) Sensor Instances OGC Catalog Service for the Web (CSW)

Virtual TEDS in OGC catalog For sensors that don’t have embedded IEEE 1451 Transducer Electronic Data Sheet (TEDS) information, the benefits of automatic configuration and calibration can also be realized through “Virtual TEDS”. That is, TEDS data can be located in a database accessible to the data acquisition system and its clients. Rather than query the sensor for its TEDS data, the client queries the database. Virtual TEDS can use an online catalog that implements the OpenGIS Catalog Services (CSW) Interface Standard.
