Scotland's wildness - ruggedness

One of four component layer of the Scottish wildness map. This layer seeks to capture ruggedness: 'landform which is rugged, or otherwise physically challenging' (Annex 1 SNH policy statement). The dataset is on a scale of 1-256 indicating relative levels of ruggedness. 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.

Statement
Data sources: NextMap DTM: 2002 This layer analyses the slope and relative relief of the terrain across Scotland based on the NextMap Digital Terrain Model (DTM). Analysis was undertaken at 50m cell resolution. For each cell the standard deviation of terrain curvature within a 250m radius is calculated, with a higher score assigned to landform which is steep and/or rough. The results were re-scaled 1-256 to produce a map of relative ruggedness and resampled to a 25m output resolution. The accuracy of the dataset is dependent upon the accuracy of NextMap. This is stated as vertical accuracy +- 1m; horizontal accuracy +-2.5m (slopes <20 degrees). However errors will have been smoothed out in resampling from 5 to 50m resolution. A fuller description of the methodology is given on the wildness internet page at http://www.snh.gov.uk/protecting-scotlands-nature/looking-after-landscapes/landscape-policy-and-guidance/wild-land/mapping/
