iNous: Building an Eco-System for Indoor Spatial Information


iNous (indoor/outdoor spatial data services) is a large research project funded by the Korean government (official webpage of the project. The main objective is to develop an eco-systems of software for:

  1. reconstructing indoor maps automatically
  2. managing these maps in an efficient way
  3. using these indoor maps in different applications

The focus of the project is on the OGC standard IndoorGML, but alternatives formats to represent the indoor of a building and its navigation graph will be sought.

What do we do?

We are responsible for 2 work packages:

1. The validation of IndoorGML files.

This implies validating the geometry, topology, and general consistency of IndoorGML files. We have extended val3dity so that the rooms/cells in IndoorGML are validated, and so that the navigation graph is also validated.

The support for IndoorGML was added in val3dity v2.2.0 (download it there).

Are your IndoorGML files valid? Hugo Ledoux. In Proceedings 15th 3D GeoInfo Conference 2020, ISPRS, 2020, pp. 109–118. BibTeX

  pages = {109--118},

2. The develop of a JSON-based encoding for IndoorGML.

Our proposal for IndoorJSON is online, with some software to convert IndoorGML files.

Open-source software and standards

  1. val3dity (v2.2+ has IndoorGML support out-of-the-box)
  2. IndoorJSON
