Statement

Dataset Source: The original GDE dataset was produced by Dresel et al. (2010) in vector format. The vector dataset was converted to a 25m x 25m raster grid by intersecting the grid with the vector dataset and querying for the presence (= 1) or absence (= 0) of a mapped terrestrial GDE. This grid was aggregated up to 100 m x 100 m grid size (i.e. 16 smaller grids were combined to 1 large grid) and the density of terrestrial GDEs within this larger grid was calculated by the number of 25m x 25m grids that recorded the presence of a GDE through the previous step. The minimum density was 0 (i.e. 0 out of 16 smaller grids recorded a GDE within the larger grid) and the maximum density was 16 (i.e. 16 out of 16 smaller grids recorded a GDE within the larger grid). Density classification was undertaken using a 1km proximity radius. The cells that did not record a GDE were excluded prior to the density classification. The final GDE dataset has been classified as follows: 0 = No Terrestrial GDE 1 = Low Density Terrestrial GDE 2 = Low-Medium Density Terrestrial GDE 3 = Medium Density Terrestrial GDE 4 = High Density Terrestrial GDE Dataset Originality: Derived
