19 February 2014 – The Open GeospatialConsortium (OGC®) IndoorGML Standards Working Group seeks public comments onthe candidate OGC IndoorGML Encoding Standard.

The candidate OGC IndoorGML EncodingStandard has been developed to provide a common schema framework forinteroperability between indoor spatial applications. These cover a widespectrum of application areas such as indoor location services, indoor web mapservices, indoor emergency control, guiding services for visually handicappedpersons in indoor space, and indoor robotics. Cross-platform, vendor-neutralcommunication of indoor spatial information is essential to meet the marketdemands of these applications. The international participants in the IndoorGMLStandards Working Group worked in collaboration with indoor navigationinformation standards groups in other standardization organizations includingISO/TC204 and IEEE Robotics & Automation Society (RAS).

IndoorGML is currently implemented asan application schema of the OGC Geography Markup Language Encoding Standard version3.2.1. IndoorGML's minimal set of geometric and semantic data elements relatedto construction components is consistent with other standards such as the OGC'sCityGML standard and buildingSMART's Industry Foundation Classes (IFCs).

IndoorGML specifies conceptual modelsand XML schema based on cellular space representation for the followinginformation about indoor space:

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

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

All OGC standards are free and publiclyavailable at http://www.opengeospatial.org/standards. The candidate OGC IndoorGML Encoding Standard isavailable at http://www.opengeospatial.org/standards/requests/117.

The OGC is an international consortiumof more than 470 companies, government agencies, research organizations, anduniversities participating in a consensus process to develop publicly availablegeospatial standards. OGC standards support interoperable solutions that”geo-enable” the Web, wireless and location-based services, andmainstream IT. OGC standards empower technology developers to make geospatialinformation and services accessible and useful with any application that needsto be geospatially enabled.
