Overview
Background to the Project
Lidar provides access to high resolution, high accuracy terrain information and as a secondary output a laser "image" of the land surface derived from measurements of the intensity of reflection of each backscattered laser pulse. Archaeological applications of Lidar have focused largely on its ability to provide a high resolution record of terrain variation, allowing the detection and mapping of subtle archaeological features mapping of fluvial geomorphology and its unique ability to penetrate vegetation cover to map underlying archaeological earthworks. Backscattered laser intensity measurements have largely escaped attention and little or no work has been undertaken to investigate intensity, which until now has been largely ignored both by archaeologists and by the lidar industry as a whole.
The Digital Archive
The digital archive is an integral part of the reporting process and comprises all files generated in electronic format generated during the course of the project, and for which permissions have been granted for deposit.
The archive contains the following reports:
- Challis, K., AJ Howard, M Kincey, D Moscrop, CJ Carey, T Hill, DN Smith, BR Gearey A Thompson, 2007. Analysis of the Effectiveness of Airborne Lidar Backscattered Laser Intensity for Predicting Organic Preservation Potential of Waterlogged Deposits. HP Vista Unpublished Report
The report comprises a brief review of the project aims and objectives (section 1: precised from the original PD), a discussion of the laboratory analysis of the relationship between NIR spectral reflectance and sediment properties (Section 2), discussion of the use of ground based laser scanning as an analogue for airborne lidar (section 3) a discussion of the analysis of airborne lidar intensity (section 4) and some general discussion and conclusions (section 5).
