EDO8271 - Proposed gravel extraction, Moreton; heritage assessment 2016

OASIS: The level to which the proposed extraction areas are visible from buildings was calculated using the open source geographic information system package ‘QGIS’. The QGIS plugin ‘Viewshed Analysis’ by Zoran Čučković was employed to ascertain which parts of the landscape were visible from points in the landscape identified by the Historic England National Heritage List (listed buildings) and the Conservation Area Appraisal (positive buildings). The surface model used in the calculations is a LIDAR Composite Digital Surface Model (DSM) with a 1m horizontal resolution, published by the Environment Agency.
