Sensor Web DesiresSensor Web 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
© Geospatial Research & Consulting© Geospatial Research & Consulting Ingo Si Ingo Simmonisonis
Sensor Web Desires IISensor Web Desires II Task sensors, when possible, to meet
my specific needs
Subscribe to and receive alerts when a sensor measures a particular phenomenon

Sensor Web Vision ISensor 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
© Geospatial Research & Consulting© Geospatial Research & Consulting Ingo Si Ingo Simmonisonis
Sensor Web Vision IISensor 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
© Geospatial Research & Consulting© Geospatial Research & Consulting Ingo Si Ingo Simmonisonis
Sensor Web Vision IIISensor 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)

What is OGC?What is OGC?
OGC Mission
To lead in the development, promotion and harmonization of open spatial standards …
Not-for-profit
International industry consortium
Founded 1994, currently 340+ members
Open Standards development by consensus process
© Geospatial Research & Consulting© Geospatial Research & Consulting Ingo Si Ingo Simmonisonis
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
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.
