Scope and Content Southdean Initially, an area about 8km in length by up to 2.5km in breadth was selected for survey on the basis of the available 1:2500 vertical air photographs; this area was subsequently adjusted to take in a larger tract of country. For the greater part of the area, film map overlays were prepared by transcribing archaeological detail from the OS air photographs, using the standard process of best-fitting the archaeological features to the map. Where no 1:2500 map existed, the relevant 1:10,000 1km square was enlarged; in order to limit transcription errors, an EDM was used to provide ground control. The remained of the are a was recorded at 1:10000, as the paucity of archaeological remains did not merit more detailed treatment. As on Waternish, Skye aerial photograph transcription was carried out for areas which had already been afforested, in order to record the context of surviving remains (e.g. White Hill NT60NE 01). The field survey was undertaken by a team of two fieldworkers (an investigator and a surveyor) and was carried out on an intermittent basis between February 1991 and May 1992, with a final check of some sites in December 1992. Features were recorded in standard Afforestable Land Survey style. EDM ground survey was used to supplement the areas not covered by the 1:2500 air photographs and to add detail not visible on the air photographs. The final drawn film overlays were digitised into Autocad several years after the completion of the survey.
