The document discusses using FME to produce Indoor Mapping Data Format (IMDF) datasets. It describes a proof of concept project to create an indoor map for a large German hospital with over 7,000 staff and 1,500 beds. The project involved mapping two levels of the hospital and addressing challenges like integrating complex and heterogeneous input data, georeferencing, modeling spaces and openings, and maintaining topology. Automating the IMDF production process using FME helped overcome these obstacles. Next steps include reducing validation errors and adding more data like amenities.
