Tools
Once the records are in place, we build the tools each excavation needs to read them back: the site in 3D, the Harris Matrix, phases and periods, material density, Munsell colours, LiDAR with total station points. They read straight from the workspace, with nothing to export.
- Can we bring LiDAR scans, orthophotos and drone models?
- Yes. LiDAR scans and orthophotos are georeferenced by setting points on them and entering their total station coordinates; with three or more points you can check the fit and see the error at each point. Every scan keeps its date, so a trench's scans play back on a timeline, and contour lines are drawn at whatever interval you set. Drone and camera models, orthophotos and LiDAR all sit in the same 3D space as your units and finds.
- Can we record Munsell soil colours?
- Yes. Hue, value and chroma are recorded as fields of their own on stratigraphic units and finds, not buried in a description, and the 3D scene uses them to colour each unit and find, so changes in the deposit show in the ground itself.
- Can we draw on our own site plans?
- Yes. Place and scale a photographic excavation plan in the 3D scene and draw stratigraphic units directly onto it; the plan stays in place as a reference while you map the units.
- Do we need special equipment for the LiDAR photo plans?
- The daily 3D photo plans at Torre dell'Alto were taken with the LiDAR built into an iPad, then georeferenced with the day's total station export. Following the trench's progress this way needs an iPad Pro or iPhone Pro with LiDAR.
