observer directed
Definition
- Conventional three-band photography from an airborne platform. Its operating principle is based on the detection of reflected electromagnetic radiation between 400 nm and 700 nm (i.e. light), sometimes extended with one near-infrared band (between 700 nm and 1100 nm). In archaeology, the observer-directed approach is often used from the cabin of a low-flying (anywhere between 300 m and higher) aircraft. After an archaeological or environmental feature of interest is detected, it is orbited and photographed from various positions. Since this type of archaeological aerial prospection primarily generates oblique images (or simply ‘obliques’) of archaeological interest, archaeologists have used ‘oblique survey’ as shorthand for this type of observer-directed or observer-biased survey strategy.
