Bridging the Gap between BIM and GIS with Open Source Software

Traduttori traditori (“translators traitors”) or the difficulty of converting data

BIM – the Building Information Model – can describe many aspects related to the construction and the management of buildings and built infrastructure. It seems only natural to connect information from BIM files to data in Geographical Information Systems (GIS).
Many fundamental differences make this task more challenging as you might expect and requires a deeper transformation of concepts from the world of buildings to GIS.
As a final step in the translations, a GeoSPARQL extension was developed for the well known Open Source software Ontop, which allows to access geographical data in a PostGIS database as linked Data.
These activities were performed within the ERDF funded project GEOBIMM.
