Derived using Zonal statistics in ARCGIS to summarise the original SDTM_v5 (2010) dataset. Each hexagon cell in this dataset has a side length of 1km and area of 2.6 km sq. Attribution includes Mean thickness from BSTM and ASTM models, Mean extrapolation distance (DBUFF), Range and Maximum of the BSTM model and percentage cover of models for each hexagon.
