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
![Page 12: Sensor Web: OGC‘s Point of View](https://reader036.fdocuments.us/reader036/viewer/2022062411/56815633550346895dc3dc41/html5/thumbnails/12.jpg)

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
![Page 13: Sensor Web: OGC‘s Point of View](https://reader036.fdocuments.us/reader036/viewer/2022062411/56815633550346895dc3dc41/html5/thumbnails/13.jpg)

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)
