Publications

These are our publications since the Lab was established in 2019 (earlier publications of the PI of the Lab Dr Filip Biljecki are available here). We strive to publish open access papers whenever possible. The PDFs available here are either published as gold or green open access (usually postprints). For the authoritative publication please visit the publisher’s website linked through the DOI of the article. For code and data check our Github page or follow the links noted in the publications.

Please note that this list does not include preprints, but frequently we post them on arXiv, so feel free to check there for our latest work that is not yet published in journals or conferences.

Visualising detailed CityGML and ADE at the building scale

There is an increasing activity in developing workflows and implementations to convert BIM data into CityGML. However, there are still not many platforms that are suitable to view and interact with the detailed information stored as a result of such conversions, especially if an Application Domain Extension (ADE) is involved to support additional information.
