Crop-Mark surveys using a drone

0

Archaeological research by the Landscape Research Centre in and around West Heslerton in Yorkshire has been in progress for 40 years. This has included intensive programmes of air photography, multi-spectral imaging and vast geophysical surveys. New drone technologies offer the opportunity to examine crop-marks at 1-2 centimetre resolution greatly enhancing our understanding of sites many not seen for many years. The drone surveys are adding detail not previously recorded to a range of 'sites' observed using different technologies for 4 decades. The very long and wet winter of 2017/2018 combined with a long hot dry spell from May to July 2018 provided the environment within which extraordinary crop-marks have become visible, some of the results can be seen here.
