These depth bands were picked because they represent the horizons that have impact on offshore infrastructure deployment. The map is derived from (unpublished) BGS 1:1000000 scale Quaternary digital geological mapping. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The data are held by the BGS as an ESRI Shapefile.

Polygons with attributes of less than 5m thick (offshore) were isolated and used to create this new ArcGIS shapefile of Quaternary thin cover. Polygons of areas where Quaternary thickness is less than 50 m or greater than 50 m were created using the Quaternary Thickness layer, which consists of isopach lines (polylines) of sediment thickness derived from the 1:1000000 Quaternary layer (unpublished). As these polygons originate from 1:1000000 scale maps, they are not of high resolution. The processing was done in ArcGIS 10.1. Part of this dataset, mainly around the coastline, has been coarsely interpolated so that its extent covers the whole factor map area. The methodology used to fill in no-data areas consists of dividing these areas into square grids (10x10km) where each polygon within the grid will get assigned the category value of the polygon sharing its border in an iterative process until all polygons within the grid have a category value. This iteration was done by running the ArcGIS Spatial Join tool several times with the match option “SHARE_A_LINE_SEGMENT_WITH”. The final step is merging the now attributed grid to the dataset and dissolving the polygons.
