OGC Sensor Web Standards - Goals Quickly discover sensors (secure or public) that can meet my needs – and learn about what they can do (location, observables, quality, ability to task) Obtain sensor descriptions in a standard encoding that is understandable by the user and by 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 Request and receive alerts / notification when a sensor measures a particular phenomenon, or completes a requested task

(OGC) –Not-for-profit, international voluntary consensus standards organization –Founded in 1994, Incorporated in US, UK, Australia –358 members from industry, government, research and university OGC Mission To lead in the development, promotion and harmonization of open spatial standards …

Helping the World to Communicate Geographically 10 OGC’s Approach for Advancing Interoperability Interoperability Program (IP ) - a global, innovative, hands-on rapid prototyping and testing program designed to accelerate interface development and validation, and bring interoperability to the market Specification Development Program –Consensus standards process similar to other Industry consortia (World Wide Web Consortium, OMA etc.). Outreach and Community Adoption Program – education and training, encourage take up of OGC specifications, business development, communications programs
