Abstract

3D technologies, such as photogrammetry and laser scanning have become an integral part of the preservation of cultural heritage sites. Due to the wide segment of users of these technologies, the quality of the derived 3D datasets has become a real issue and is often subjected to huge variations in accuracy and resolution.

In 2021 the vegetation on the site of Neu-Wildon was removed for extended conservation work, which was a unique opportunity for the documentation of the castle remains in 3D for the first time. At this site terrestrial and drone-based photogrammetry as well as terrestrial laser scanning have been applied by geodetic experts. In this paper the quality of the derived datasets for each technology is evaluated and their limitations are discussed.

Additionally, the usability of the 3D technologies and the derived 3D models for building research is demonstrated at the example of the virtual reconstruction of the appearance of the castle Neu-Wildon at the end of the 16th century.
