  3. Ⅰ Introduction Background • Aiming at the increasing demand of indoor and outdoor seamless navigation and location service, a Chinese standard of Multi-dimensional IndoorLocation Information Markup Language(IndoorLML)is proposed, which defines the ontology of indoor location information based on the CityGML and IndoorGML, and provides GML-based format for the indoor routing and navigation of different role. The Multi-dimensional Indoor Location Information Model is the core of the Markup Language.

  4. Ⅰ Introduction RelatedWork

  5. Ⅱ Requirements • TheoreticalRequirements *80%-90% of the time is in the indoor The outdoor map is difficult to meet the needs of indoor activities *80% of the human data connection from indoor

  6. Ⅱ Requirements • TheoreticalRequirements Location-based service on mobile devices still utilize traditional map with contextual noise.Especially for indoor environment, the hierarchic spatial information needs to be provided to users.

  7. Ⅲ Indoor Location Model • Use caseof Indoor Location Model

  8. Ⅲ Indoor Location Model • Indoor Location Model Indoor Location’s representation is based on Absolute Location and Relative Location Absolute Location: A point or an abstract region that is measured with respect to the origin of a standard coordinate system in geo-graphic space or in context. Relative Location: A position that is measured or described with respect to another location, not the origin of the coordinate system.

  9. Ⅲ Indoor Location Model • UML Diagram of Indoor Location Model

  10. Ⅳ Example of Using Indoor Location • Indoor Structure of Example Model Semantic Location of Example Model Relation of Semantic Location

  11. Ⅳ Example of Using Indoor Location • Indoor Navigation Based on Indoor Location

  12. Ⅳ Example of Using Indoor Location • Indoor Navigation Based on Indoor Location

  13. Ⅴ Conclusion and Future Work • Conclusion The Indoor Location Model has the potential capacity to describegeometrical location and semantic location of indoor environment, aiming at different user groups and information needed for different tasks. • Future Work • The extension and improvement of the Indoor Location Model • The Multi-dimensional Indoor Location Information Standard of China • Example of dynamic environment indoor navigation

  14. Ⅴ Conclusion and Future Work Example of dynamic environment indoor navigation • Indoor Emergence • Indoor Routing
