Abstract: |
A temporary grid system will be established over the site and marked out using canes. The location of the grid will be set out using an RTK GPS system theoretically accurate to some 0.01m and referenced to OS co-ordinates. Hand Held: Data will be collected using a Bartington Grad 601-2. The instrument consists of two paired sensors (see below) and readings are logged at 0.25m centres along traverses 1.0m apart across 30m grids. The collection of data at 0.25m centres provides an appropriate methodology balancing cost and time with resolution as per Historic England guidelines. Two 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. The magnetic survey at Braunston Road, Oakham has identified an enclosure recorded in the HER. Measuring some 65m x 75m the rectilinear feature with rounded corners appears to have an entrance in the south-east corner. There are suggestions of internal features but the results are partially obscured by ridge and furrow cultivation ploughing which extends across the site. There are a few uncertain responses in the data, some of which could be archaeological. Former field boundaries are visible where the ridge and furrow patterns change orientation. A modern service pipe crosses the survey area. |
