The OGC invites comments on the candidate IndoorGML navigation standard


Wednesday, 19 February 2014 UTC

19 February 2014 - The Open Geospatial Consortium (OGC®) IndoorGML Standards Working Group seeks public comments on the candidate OGC IndoorGML Encoding Standard.

The candidate OGC IndoorGML Encoding Standard has been developed to provide a common schema framework for interoperability between indoor spatial applications. These cover a wide spectrum of application areas such as indoor location services, indoor web map services, indoor emergency control, guiding services for visually handicapped persons in indoor space, and indoor robotics. Cross-platform, vendor-neutral communication of indoor spatial information is essential to meet the market demands of these applications. The international participants in the IndoorGML Standards Working Group worked in collaboration with indoor navigation information standards groups in other standardization organizations including ISO/TC204 and IEEE Robotics & Automation Society (RAS).

IndoorGML is currently implemented as an application schema of the OGC Geography Markup Language Encoding Standard version 3.2.1. IndoorGML's minimal set of geometric and semantic data elements related to construction components is consistent with other standards such as the OGC's CityGML standard and buildingSMART's Industry Foundation Classes (IFCs).

IndoorGML specifies conceptual models and XML schema based on cellular space representation for the following information about indoor space:

  • Geometric and semantic properties of spaces and connectivity
  • Navigation context and constraints
  • Space subdivisions and types of connectivity between spaces
  • Navigation networks (logical and metric) and their relationships

The IndoorGML Standards Working Group (SWG) will consider all submitted comments for changes to the final draft of the IndoorGML Standard. The 30-day comment period ends March 21, 2014.

All OGC standards are free and publicly available at The candidate OGC IndoorGML Encoding Standard is available at

The OGC is an international consortium of more than 470 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled. Visit the OGC website at
