Abstract
P355 Analysing Potential Field Data Using Visibility Summary 1 The viewshed of a topographic dataset is the region around a given observation point that is visible from that location. It has many uses such as in the siting of television transmitters or in determining the visible impact of changes to the environment on the surrounding area. The viewshed is used here as a data enhancement tool to aid in the interpretation of geophysical potential field data. The fraction of the area of a moving window visible from each point on the dataset (considered as if it were topography) is computed.
