Kent National Mapping Programme project
The Kent project had its origins in the Kent Air Photo Survey undertaken by the Air Photography Unit (APU) of the Royal Commission on the Historical Monuments of England (RCHME) during 1986-1987. The survey, partly funded by English Heritage, produced 1:10,000 scale maps of cropmarks for Kent, accompanied by written descriptions in what is now the National Record of the Historic Environment (NRHE). The maps and descriptions were also intended to form part of the first county Sites and Monuments Record for Kent.
A pilot project
Because it was a pilot project, one of four that helped define the processes used in future NMP projects, its scope and methods were more limited than would now be the case. For example, only plough-levelled archaeological features visible as cropmarks and soilmarks were mapped, and vertical photography was little-used. The bias in the number and type of sites recorded can be seen in this distribution plot.
Cropmark Classification Project
The 1:10,000 scale cropmark transcriptions were the raw material used in the development of the APU’s Cropmark Classification Project between 1987 and 1989. Again partly funded by English Heritage, the project’s central aim was to produce a classification system for cropmarks that could be used in the process of identifying sites for protection.
Various site types were classified according to their morphology and compared against known examples.
The results of the project continue to inform aerial reconnaissance and interpretation in Kent.
