| Abstract: | As part of the Wychwood Project in West Oxfordshire, England, aerial photography and historic maps are being used to reconstruct landscape change in the former medieval Royal Hunting Forest of Wychwood. An important objective of the project is to stimulate local interest in Wychwood and promote understanding of its evolution, thereby encouraging the support of stakeholders in the design of future landscapes. The parish of Leafield was selected to develop and test a method for reconstructing and visualising past and present landscapes to present to the public for evaluation and comparison. Leafield contains fine examples of both early and late enclosure landscapes and underwent large-scale disafforestation following the Enclosure Act of 1856. Ordnance Survey (O.S.) 1:10000 Landform Panorama contour data were used to create a digital elevation model (DEM) of the parish using ArcView 3D Analyst, enabling the user to create perspective views of the landscape from any height and viewing angle. Contemporary aerial photography was scanned and geo-rectified to create an overlay for 'draping' onto the DEM. Historical maps provided the reference for modifying the aerial photography using the PaintShop Pro graphics package. This paper presents and reviews the results and compares the method with other techniques, including VRML. |
