Abstract
This paper describes the use of ground‐penetrating radar (GPR) to extrapolate from data generated by a long‐term training excavation in Gloucestershire, SW England for which geophysical survey techniques including GPR had been used. Due to external circumstances beyond the control of the archaeological team, the ownership of the site changed hands and all excavation and associated investigation had to cease. However, an adjacent landowner granted permission for a GPR survey across his land. These latest GPR survey results have been used to supplement the excavation results, significantly extending the information available to the archaeological team. The data demonstrate the accuracy with which GPR data can be matched to excavation data and the improvement in target definition possible with reduction of transect spacing. The impact of some of this information is still being evaluated.
