Aerial Photography

Aerial Photography has been used for many years to identify and record archaeological sites. Depending on the lighting conditions, time of year and vegetation cover, it is possible to see a variety of archaeological features in aerial photographs including earthworks and even sub-surface features (as soil marks, crops marks or changes in vegetation).

With the advent of Remote Sensing techniques including airborne LiDAR (Light Detection and Ranging) and CASI (Compact Airborne Spectrographic Imager), aerial photograph interpretation techniques have been applied to a much wider range of source images. Both these datasets and aerial photographs can be manipulated using Geographic Information Systems (GIS) to further enhance features of interest.
 
Guidance for the transcription of aerial photographs as part of archaeological survey projects is provided by the National Mapping Programme team at English Heritage and all our work is undertaken to their standards. Such work is often carried out as part of Historic Environment Record (HER) enhancement projects in order to add to the archaeological records held by local authorities.
