GeoWeb on Mobile Internet 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 Requirements and Space-Event Modeling for Indoor Navigationfor 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 ThingsInternet 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 VisionSensor 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

Observations and MeasurementsObservations 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]
