  1. Sensor Web: OGC‘s Point of View Ingo Simonis Freelancer

  2. What is a Sensor?

  3. Geosensor Networks • Location awareness • WHERE is the sensor, WHERE is the observable

  4. Size does not matter …

  5. What is the Sensor Web? • A number of definitions...

  6. Was ist das Sensor Web? Slide by NASA

  7. Scientific View: Sensor Web Applications Communication Sensor Web Communication Sensor Network Communication Sensor System Communication Sensor

  8. OGC: Sensor Web

  9. Sensor Web Desires • Quicklydiscover 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

  10. Sensor Web Desires II • Task sensors, when possible, to meet my specific needs • Subscribe to and receive alerts when a sensor measures a particular phenomenon

  11. Sensor Web Vision I • Sensors will be web accessible • Sensors and sensor data will be discoverable • Sensors will be self-describing to humans and software (using a standard encoding) • Most sensor observations will be easily accessible in real time over the web

  12. Sensor Web Vision II • Standardized web services will exist for accessing sensor information and sensor observations • Sensor systems will be capable of real-time mining of observations to find phenomena of immediate interest • Sensor systems will be capable of issuing alerts based on observations, as well as be able to respond to alerts issued by other sensors

  13. Sensor Web Vision III • Software will be capable of on-demand geolocation and processing of observations from a newly-discovered sensor without a priori knowledge of that sensor system • Sensors, simulations, and models will be capable of being configured and tasked through standard, common web interfaces • Sensors and sensor nets will be able to act on their own (i.e. be autonomous)

  21. What is OGC? • Not-for-profit • International industry consortium • Founded 1994, currently 340+ members • Open Standards development by consensus process OGC Mission To lead in the development, promotion and harmonization of open spatial standards …

  22. OGC Program Interoperability Program – a global, innovative hands-on rapid prototyping and testing program designed to accelerate interface development and validation and to 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 Slide by OGC
