OGC: Sensor WebOGC: Sensor Web


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


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


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


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


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.
