Digital Terrain Modelling
Also known as Digital Elevation Modelling, Digital Terrain Modelling (DTM) allows the visualisation of the surface of monuments and archaeological features. By accurately measuring the land surface using GPS or a total station, detail can be expressed as a digital image or as contours.
A range of functions can be carried out on the data to enhance certain visual aspects of the model such as height exaggeration and lighting effects. The model of Castel Combe castle below was produced from data collected in dense woodland and the site can now be visualised as never before.
