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)

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]
