AutoCAD file of excavation trenches, features, merged photographs used for planning, and geophysics rasters. The total station data in the drawing is reduced from the total total station data that can be found in the LISCAD file 'Thwing_4-4_total_station_data.see'. The layer names for contexts and features are arranged as: Phase_Featuretype_Featurenumber_contexttype_origin. For example: layer '1b_Pit_1.4_cut_203_fill_196_digitised_from_photos' is Phase 1b, Pit 1.4, representing the cut number 203 and fill number 196, which has been drawn/digitised from planning photographs linked to the dwg.
