The Savernake Forest NMP project was designed as a multi-disciplinary project to assess the efficacy of using lidar for surveying in woodland. It consisted of a desk-based survey using the standard National Mapping Programme (NMP) methodology of looking at all readily available aerial photographs together with the results of a lidar survey commissioned from the Unit for Landscape Modelling at Cambridge University (ULM) by the Forestry Commission. The lidar survey covered only the main area of Savernake Forest extending from the outskirts of Marlborough to the Kennet and Avon Canal, but the NMP survey was extended to include all 1km squares covered by part of the lidar survey. This produced a project area of 54 km2 covering 5 Ordnance Survey 1:10,000 scale quarter sheets, the extents of which are defined in GIS. Completion of mapping from the lidar data was followed by limited fieldwork to assess and characterise results. This took the form of some general survey to assess the accuracy of the lidar data in revealing features on the ground and assessing whether they were of archaeological origin together with a small area of detailed survey to assess both the interpretational accuracy and also the specific metrical precision of the lidar data. In both cases the data was found to be very accurate.
Whilst the lidar data and the standard aerial photographs were examined together, and the information from both will be combined for the final maps and records, part of the aim of the project was to assess how much information came from each individual source and how much was recoverable from both; this will form a large part of the resulting management report and should help to inform future use of lidar data in wooded areas. To this end the project was carried out in close co-operation with staff from the Forestry Commission who had carried out some analysis of the lidar data for management purposes prior to the beginning of the project.
