This technique of landscape analysis had been somewhat restricted until recently because of legal controls. Nevertheless, important work was undertaken by John Bradford and John Ward-Perkins on cemeteries and road networks respectively, using RAF photographs. In addition, Italian scholars well connected with the Aeronautica militare, such as Giulio Schmiedt, made very substantial early contributions. Their past and present collective achievements are to be seen in the Aerofototeca Nazionale of Rome, now interpreted by highly sophisticated modern techniques. More recently, LiDAR (light detection and ranging) has been deployed using laser techniques by the Universities of Cambridge and Siena to model ancient landscapes in the Faliscan and Tuscan areas of Etruria.
