This report documents a project based on developing a prototype as a solution to extract and manage indoor data from IFC files and demonstrate the use of it in a navigation app.

The project continues the work done in the preceding semester, in terms of both improvements and extensions. Completion of the prototype back-end is done by altering the extraction process to remove found errors, enhancing the mapping procedure to provide significantly better results, harness the advantages of using a spatial database, and adding useful features to the back-end UI. Additionally, a partition decomposition algorithm is refined and implemented to avoid dead space in the R-tree used by a spatial index.
A front-end has been developed as an app with indoor navigation features. This includes the development of a routing functionality and a novel method to calculate intra-partition distances, which is evaluated through experimental tests.
