Goal of Sensor Web Enablement Working Group
Quickly discover sensors (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
