Relative visibility of Scotland’s coastal marine areas from the land (Viewshed analysis)

Marine Scotland Information NMPi icon

The Viewshed tool in ArcGIS has been used to develop a GIS layer, with approximately 30 m resolution, showing the visibility of locations in the sea in terms of the number of buildings with a view of any given location i.e. the higher the number the more buildings that can see that marine location from the land.

The analysis is featured in the paper  O’Higgins. et al. (2018) ‘Many Points of View?: Visibility Mapping for Marine Spatial’, 13, pp. 302–314. doi: 10.2902/1725-0463.2018.13.art18. 

FAME and STAR seabird tracking - Common guillemot (Uria aalge) (at-sea distributions, Scotland only)

Marine Scotland Information NMPi icon

UK-level utilisation distributions (UD) for Guillemot. UDs are provided in a sequence of 5% contours for each species starting at the 5% utilisation distribution and ending at the 95% utilisation distributions. Within the ecological literature the 95% UD is often used to define the 95% home range of a species and the 50% UD is used to define the 50% core range of a species.
