Indoor Location

Key OGC activities and reports on Indoor Location

IndoorGML

A current focus of this work is IndoorGML.  IndoorGML builds on the work summarized below.  A sample of the IndoorGML concepts was presented by Thomas Kolbe (CityGML editor) in late 2011:

     
This presentation gets a bit into the math weeds, but it shows that a key topic is the overlap of architectural models with wi-fi maps.
Formation of an OGC Standards Working Group for IndoorGML will be reviewed and probably approved in 2012.

OGC Summit on Indoor Location, Navigation, and Floor plans

http://www.ogcnetwork.net/node/624

This special session of the OGC 3DIM (3D Information Management) Working Group brought together professionals representing multiple standards development organizations or activities related to defining encoding standards for expressing indoor location, floor plans, and other built environment information required by information communities such as emergency services, outdoor/indoor navigation, and augmented reality. Summit was held in December 2009.

OWS-6 Outdoor and Indoor 3D Routing Services Engineering Report

The OGC Web Services Testbed, Phase 6 (OWS-6) conducted in 2009 developed prototype extensions to CityGML for outdoor and indoor routing: "CityGML is the accepted standard for describing 3D data sets for city environments, including buildings. But CityGML does not currently include a data model for routing information. By adding the network topology, efficient path routing between the outdoor and indoor environments can be seamlessly performed."

OGC Call for Comments on Discussion Paper on Indoor Navigation

Press Release: http://www.reuters.com/article/2011/04/11/idUS223215+11-Apr-2011+MW20110411

Discussion paper: http://portal.opengeospatial.org/files/?artifact_id=41727

The OGC sought comments on an OGC discussion paper, "Requirements and Space-Event Modeling for Indoor Navigation." The OGC seeks
to facilitate the development of interface and encoding standards and best practices that enable seamless connection of indoor and outdoor
location in applications of all kinds. The discussion paper presents a model for indoor navigation that simultaneously addresses route planning, multiple localization methods, navigation contexts, and different locomotion types. The results of this Call for Comments has led to the startup of the IndoorGML Standards development.

The Internet of Things and Indoor Location Standards

OGC has significant activity in the area of Internet of Things. We led two workshops and engaged with several communities, e.g, raising awareness at:

OGC Coordination with IETF

Related to the work of the OGC, the IETF GeoPRIV Working Group has had numerous discussions and standards development work focused on indoor location and navigation. An interesting set of requirements is related to relative navigation as opposed to absolute navigation. An example of relative navigation is "Take elevator 1 to the 4th floor, turn right and go three offices on the left to room 406". There is an internet draft describing this work. http://tools.ietf.org/html/draft-ietf-geopriv-relative-location-01
