Description
IndoorGML is the OGC standard schema for representing indoor space — cells, doors, navigable graphs, and multi-floor connectivity — in an interoperable XML form. It matters to this thesis because the GIS-mapped monitored area in the testbed needs a vendor-neutral indoor representation against which BLE trajectories, CSI sensor positions, and crowd-flow vectors can be aligned, and because IndoorGML is the de-facto reference for indoor spatial models in the wireless-sensing literature.
When it's used
- Indoor space modelling for crowd-flow / evacuation simulation
- Mapping CSI / BLE infrastructure onto navigable indoor topology
- Bridging vendor-specific BIM models to standard navigation graphs
Limitations
- Adoption is uneven — many systems still rely on bespoke JSON / GeoJSON
- 3D / multi-floor extensions add modelling complexity
- Tooling lags behind CityGML / BIM ecosystems
