Survey data recording the excavations and the reference points for photogrammetric models. The trench was located just north of the Lion mosaic, in order to re-investigate Victorian excavations of a Roman domestic bath suite in the north-west part of Building 4.8. These excavations are listed as G104 in the Gazetteer. The data is available in two forms: text files and shapefiles. The text files are organised into GPS and TST (total station) folders. Within these, the data is organised by date, and can be cross-referenced with the survey notebook that accompanyies the data as a pdf.
