consensus standards organization; leading
development of geospatial standards
• Founded in 1994.
• 480+ members and growing
University
24%
• 33 “core” standards
• 15 extensions/profiles
• Hundreds of product
implementations
• Alliances and collaborative
activities with ISO and many

Sensor 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 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 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 II

Standardized web services will exist for
accessing sensor information and
sensor observations

Sensor systems will be capable of realtime 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 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 networks will be able
to act on their own (i.e. be autonomous)

of sleep is low, the light cannot be turned on
and room temperature will be set to 15 degree

Why OGC?
Every thing has a location
Location information needs to be carefully
described.
e.g., outdoor, indoor, geometry, topology,
semantics, sensor space, etc.
OGC Sensor Web Enablement is widely
adopted and implemented
e.g., OGC/ISO Observation and Measurements,
OGC SensorML, OGC Sensor Observation
Service, etc.
The OGC SensorThings API is built based on the
OGC SWE

Example: GML Point Profile
Describe the location of a THING using geographic
coordinates
<gml:Point srsName=”urn:ogc:def:crs:EPSG:6.6:4326”>
<gml:pos>45.256 -110.45</gml:pos>
</gml:Point>

Example: OGC CityGML
Describe the location of a THING in a
building
– Semantic 3D city and building
models provide
• the geometry and
• a thematic differentiation of the
indoor areas (at least separation
in building parts, levels and
rooms)

Example: OGC Indoor GML
Describe the location of a THING indoor
