Orchard Farm, Land East of Upton Snodsbury Road, Pinvin, Worcestershire

A temporary grid system was established over the site and marked out using canes. The location of the grid was set out using an RTK GPS system theoretically accurate to some 0.01m and referenced to OS co-ordinates. Data was collected using a cart carrying four paired Bartington magnetic sensors. Four sensors mounted 1m horizontally apart and very accurately aligned to nullify the effects of the earth's magnetic field. Readings relate to the difference in localised magnetic anomalies compared with the general magnetic background. Each data point is geographically referenced using an on-board Trimble RTK survey grade GPS system. Readings were taken at 0.125m centres along traverses 1.0m apart. Readings relate to the difference in localised magnetic anomalies compared with the general magnetic background. The magnetometer survey has not recorded any magnetic responses that could be interpreted as being of definite archaeological interest. A number of linear and curvilinear trends of uncertain origin are visible in the survey; they are likely to have been caused by geological or agricultural processes. Four former field boundaries have been detected in the survey along with ridge and furrow cultivation. Land drains have been plotted in Area 2 and the route of a service pipe has been marked in Areas 4 and 5. Zones of magnetic disturbance have also been detected which have been caused by spreads of modern debris.
