The Derbyshire and Peak District Aggregates Assessment Project is a multi-disciplinary study, one component of which is the aerial photographic interpretation and mapping, which forms part of the National Mapping Programme (NMP). The project was funded by English Heritage's ALSF and managed by Archaeological Research Services Ltd (ARS) in partnership with English Heritage. The project partners are Derbyshire County Council and the Peak District National Park Authority. The project area comprises 376Km2 (36 part quarter sheets). The aerial survey mapping component began on 1st May 2008 and was completed on 15th June 2010. The project team, employed by Archaeological Research Services Ltd, was based in the English Heritage York office.The aim and scope of the aerial photographic interpretation was to interpret and map, at a nominal scale of 1:10,000 all levelled and upstanding archaeological features visible on air photographs dating from prehistory to the 20th Century. Air photographs will be rectified with Aerial 5.29 using control derived from Ordnance Survey 1:2500 Landline data. Archaeological features will be transcribed in AutoDesk Map 3D 2007 in the standard NMP layer system. The data are input into the AMIE database. The project created 862 new records and amended a further 256 records.
