Transforming IFC-Based Building Layout Information into a Geometric Topology Network for Indoor Navigation Assistance
Abstract
Automated navigation assistance in indoor environments requires the existence of spatial models with the ability to represent navigational knowledge of these environments. In this paper, we have built upon network-based navigation and the vector representation of road networks in GIS to create a spatial model that can be utilized for navigation guidance and erroneous positioning data correction in indoor environments. We name this spatial model the Geometric Topology Network (GTN) and have identified the requirements and developed a process for its automated creation. We have compared the strengths and weaknesses of two algorithms, namely, the Straight Medial Axis Transformation algorithm and a modified form of the Medial Axis Transform algorithm for automated creation of the GTN. The developed process for GTN creation transforms the building spaces and spatial connections represented in an IFC file into a graph network. We have also created a proof-of-concept prototype to demonstrate the automated creation of a GTN.

In visibility-based networks, there are numerous possible networks based on the different routes a person can take, unlike centerline-based approaches where there is only one consistent network for the whole building.
“As discussed in Taneja et al. (2011)), unlike the centerline-based approaches, where there is only one consistent network for the whole building, in visibility-based networks, there are numerous networks that are possible, based on the different routes a person can take.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
