Automated 3D reconstruction and the extraction of semantic information from images and image sequences are important research topics in Photogrammetry, Remote Sensing, GIS, and Computer Vision. This workshop is a follow-up to the first event under the same name embedded in the ISPRS Geospatial Week 2019 in Enschede. It will bring together experts working in photogrammetric 3D reconstruction, semantic interpretation of imagery and image sequence analysis to discuss recent developments, the potential of various data sources, and future trends in 3D reconstruction and information extraction from imagery. Its focus is on methodological research. Semantic3D will be part of the ISPRS Geospatial Week 2023, hosted by the Arab Academy for Science, Technology, and Maritime Transport, in parallel with a number of related geospatial workshops. The event will be held as a two-day single track workshop of oral presentations and poster sessions in the context of the ISPRS Geospatial Week.

Special Issue dedicated to the workshop:
After the workshop, authors of selected papers will be invited to submit extended versions of their papers to the journal PFG – Journal of Photogrammetry, Remote Sensing and Geoinformation Science (https://www.springer.com/journal/41064); current impact factor: 3.292). The papers being accepted after the peer-review process of the journal will appear in a special issue of that journal dedicated to this workshop.
