<DIV STYLE="text-align:Left;font-size:12pt"><P><SPAN>Visual Resource Mapping was carried for the Seascapes Character Assessment (2020) project to produce this dataset Land with Sea Views (LWSV). Land with Sea Views (LWSV) data considers land surface locations (500 m grid cell size), and how visible a point on land is from the sea. A grid of observation points at 500 m intervals, extending 35 km offshore from the coastline, are used to represent theoretical viewers who can visually observe the land from the sea. Height elevation of land surface locations are based on Copernicus EU-DEM v1.1 data, to which a visibility height value of 2 m (i.e. height of a 2 m tall human) is added, such that each onshore cell is calculated at HEIGHT ELEVATION + 2 METRES. A maximum viewing distance of 35 km is used. The visibility analysis assigns each land raster grid a value based on the number of offshore observation points that are visible to it. Grid cells on the land surface (coastline to 20 km inland) with high values can see and be seen by many observation points on the sea and have a higher visibility of the sea. Visual Resource Mapping conducted using methodology outlined in National Seascape Assessment for Wales LUC Report (Natural Resources Wales 2015) and Seascape Assessment for the South Marine Plan Areas (MMO 2014). Regional Seascapes Character Assessment (2020) project was carried out by Minogue and Associates on behalf of the Marine Institute</SPAN></P></DIV> |
