IndoorGML SWG | OGC(R):

Scope of Work
The scope of work for this SWG is to develop a candidate standard of a GML 3.2 application schema for indoor navigation and progress it to the state of an adopted standard by using OGC RFC process as follows;

• development a candidate of OGC standard for indoor navigation: this candidate standard, called tentatively IndoorGML will provide a GML application schema for exchanging information related to indoor navigation,

• gathering comments from SWG member on the draft of candidate standard and reflecting them to the candidate standard,

• submitting the candidate standard to OAB for review and subsequent release for the 30-day public comment,

• resolving the comments from OGC members, and

• submitting the final version of candidate standard to the OGC TC for voting.

The aim of IndoorGML is to represent and exchange the geoinformation that is required to build and operate indoor navigation systems. IndoorGML will provide the essential model and data for important applications like building evacuation, disaster management, personal indoor navigation, indoor robot navigation, indoor spatial awareness, indoor location based services, and the support for tracking of people and goods. IndoorGML provides a framework for the flexible integration of different localization technologies and allows the ad-hoc selection of the appropriate navigation data according to the capabilities of the mobile device and the offered localization technologies of a building.
Indoor navigation comprises route planning, localization, and tracking of subjects (i.e. people) and objects (e.g. robots or other indoor vehicles). IndoorGML will support these activities in different modes of locomotion, i.e. walking, driving, and flying as well as navigation in virtual environments. Since there is no unique localization technology like GPS available indoors, many different types of indoor positioning techniques are used today, often in combination with each other. This makes it necessary to provide geospatial data about the different senders, receivers, and sensors and their respective signal ranges.
Existing standards for the representation of 3D building models like IFC or CityGML do not address these aspects. From the perspective of IndoorGML they can be considered as important data sources for the interior topography of buildings (and other structures like tunnels). IndoorGML, which will be also an application schema of GML, will be thus a complementary standard to CityGML and IFC to support location based services for indoor space, particularly indoor navigation. This candidate standard will mainly consist of two components; first an indoor spatial data model given by a multi-layer space model to describe different contexts of indoor space, and the representation of indoor symbolic space and topological properties, building upon the former component.
The requirements and use-cases for this candidate standard are given in detail in the OGC discussion paper (OGC 10-191r1).
