Application and analysis capabilities of 3D data sets generated through UAV photogrammetry are presented on the basis of an exemplary millstone quarry of the so-called Mayen quarry district (Germany). In general, millstone quarries are technical cultural heritage sites which give evidence for economic interpretations as they are of interest for the reconstruction of ancient procurement patterns. Particularly those quarries which had a high economic impact cover large areas with often arduous accessibility. Therefore, photogrammetric recording using a UAV is the best approach for fast and inexpensive high-quality documentation. The images are used to create a 3D data set and orthophoto. For analysis and interpretation the Spatial Image analysis and Visualisation Tool (SIVT) of i3mainz is used allowing a variety of interactive visualization functionalities. The 3D data are transformed into 2.5D data enabling segmentation of spatial information and volume calculations. Both functionalities support the cultural heritage expert's research: On the one hand the interactive segmentation allows producing a map of the quarry displaying only those parts associated with the extraction. On the other hand the output of the quarry including debris and millstone blanks can be calculated easily. All in all, the entire workflow beginning with data capture using a UAV followed by data processing, (2.5D / 3D) data analyses and visualisation of the results is presented.
