Data for recreation (with adjustments) of Wheatley's 1996 long barrow viewshed analysis

<p>Following Wheatley's (1996) viewshed analysis of real and simulated long barrows in two regions of Wiltshire, this study aimed to replicate the analysis (investigating regional variation in barrow viewsheds) with the additional factor of elevation included to limit the random generation of long barrows to elevations where they have been observed, to avoid potential skewing of viewshed areas.</p> <p>This dataset contains 20x20km squares surrouding Avebury and Stonehenge which match Wheatley's demarcated 'subregions;' as well as polygons matching the elevation ranges within which long barrows were found in each subregion; random points generated in these subregions; the calculated viewshed areas for real and simulated barrow points, and a complete dataset for long barrows recorded on the Wiltshire HER, both certain and potential. To carry out a viewshed analysis with this data, a DTM is also required.</p>
