Title

Scotland's wildness - absence of modern artifacts

Alternative title(s)

ztv_unlog_256

Abstract

One of four component layer of the Scottishmap of relativewildness. This layer shows the level of modern artefacts (detractors)that are visible. The dataset is on a scale of 1-256 indicating relative levels of visual influence. Consequently the data is best viewed at a national or regional scale. The methodology is adapted from the 2008 Wildness Study in the Cairngorms National Park. NextMap Digital Surface Model (DSM) gives the height of the surface including the detractors from which a viewshed can be produced. Viewsheds up to 15 km were created for 3 feature layersat 50m resolution, 1) Buildings and other structures, 2) Railway lines, roads and tracks and 3) Pylons and ski lifts. A fourth viewshed up to 30 km was created for wind turbineswhose heights were added to a DTM. The resulting calculations were then re-scaled 1-256 to produce the map of lack of built human artefacts.

Lineage

Data sources: OS MasterMap for buildlings, railway lines, roads, tracks, pylons: 2014 SNH, RenewablesUK and OS Points of Interest for wind turbine locations: Dec 2013 The 4 layers were processed in the voxel viewshed tool developed by Leeds University, based on the resampled NextMap DSM. All 4 layers were processed at 50m resolution. Normalised unlogged values from the viewhsed tool were used. The four layers were added together and then the values logged. The accuracy of the dataset is dependent upon the completeness, spatial accuracy and date of all the above sources. http://www.snh.gov.uk/protecting-scotlands-nature/looking-after-landscapes/landscape-policy-and-guidance/wild-land/mapping/
