6. OGC Web Services (OWS)
Just as is the dial tone of the World Wide Web, and html / xml are the standard encodings, the spatial web is enabled by OGC standards:
Web Map Service (WMS)
Web Feature Service (WFS)
Web Coverage Service (WCS)
Catalogue (CSW)
Geography Markup Language (GML)
Web Map Context (WMC)
OGC KML
Others…
Relevant to geospatial information applications: Critical Infrastructure, Emergency Management, Weather, Climate, Homeland Security, Defense & Intelligence, Oceans Science, others

9. 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

10. Sensor Web Enablement (SWE)
Copyright © 2008, Open Geospatial Consortium, Inc., All Rights Reserved.

11. 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

12. 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

13. 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)

16. 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.
