Abstract
AbstractThe recognition of subsurface soil disturbances that have no surviving surface displacement often depends on an anomalous growth of the crop that overlies them. These disturbances are sometimes evidences of man's past activities. The very slight differentials of colour and height in growing crops are frequently difficult to record through a normal film and filter combination. In order to test the capacity of the multispectral technique, a four camera sensor was flown over archaeological sites in central southern England in the summer of 1970. Known sites were used in various geological settings, producing growth marks of differing characteristics. The sensor included the near infrared and this showed distinct advantages at the early stages of cereal growth.
