GeoWeb on Mobile Internet
• Geospatial data on web now common and transformative
– Access to information for any location and make plans based on it
– From mapping/navigation to advanced environmental studies
– GeoWeb enabled by open standards
• GeoWeb moving to mobile internet platforms
– Soon, if not already, predominant method to access the Internet.
– Dramatic advances in communications and handheld devices.
• Multiple generations of GeoWeb and Mobile

Going beyond initial generation of Location Based Services
Recent social networking based on location
But, its not just about maps, directions and checkin.
Enable augmented understanding of our geospatial reality

Requirements and Space-Event Modeling
for Indoor Navigation
• Support for multiple localization methods/infrastructures
– This includes support for arbitrary indoor sensor technologies and their
abstraction, e.g. WiFi, RFID, Bluetooth, or Infrared as well as support for the
ad-hoc selection of technologies used by the portable end-user device.
• Support for different navigation contexts
– The navigation context comprises the type of locomotion, navigation
constraints according to different criteria (e.g.: topographic/geometric
constraints, such as door widths, opening directions of doors, zonal
constraints such as security zones, or temporal access constraints such as
opening hours) and the supported localization technique.
• 3D topographic representation of the interior built environment
– This is required for route planning and derivation of navigable route section from a
model of the indoor built-up space. The representation should avoid duplicating
existing concepts and, thus, should be com- plementary to existing standards like
CityGML, IFC, X3D, ESRI BISDM, etc.

Internet of Things
• The Internet of things, also known as the Internet of
objects, refers to the networked interconnection of
everyday objects
(Wikipedia)
• A new era of ubiquity, where
– “Users” of Internet will be counted in billions
– Humans may become the minority as generators and
receivers of traffic.
– Most traffic will flow between devices and all kinds of
“things”, thereby creating a much wider and more
complex Internet of Things.
(From “The Internet of Things”, ITU Internet Report 2005)

Sensor Web Enablement - Basic Vision
• Quickly discover sensors and sensor data (secure or
public) that can meet my needs – based on location,
observables, quality, ability to task, etc.
• Obtain sensor information in a standard encoding that is
understandable by my software and enables assessment
and processing without a-priori knowledge
• Readily access sensor observations in a common manner,
and in a form specific to my needs
• Task sensors, when possible, to meet my specific needs
• Subscribe to and receive alerts when a sensor measures a
particular phenomenon

OGC SWE Specifications
• Information Models and Schema
– SWE Common – common data models used throughout SWE specs
– Sensor Model Language (SensorML) - Models and schema for
observation processes: support for sensor components and systems,
geolocation, response models, post measurement processing
– Observations and Measurements (O&M) – Core models and schema for
observations; archived and streaming
• Web Services
– Sensor Observation Service - Access Observations for a sensor or sensor
constellation, and optionally, the associated sensor and platform data
– Sensor Alert Service – Subscribe to alerts based upon sensor
observations
– Sensor Planning Service – Request collection feasibility and task sensor
system for desired observations
• Version 2.0 of SWE Specifications currently being released

Observations and Measurements
• An observation feature binds a result to a feature of interest, upon
which the observation was made
• Observation - act of observing a property or phenomenon, with the goal
of producing an estimate of the value of the property.
• Observations are modeled as Features within the context of the
General Feature Model [ISO 19101, ISO 19109]
