Abstract

The data represents the possibility that the substrate is rocky. It was created from the averaged topographic relief layer. The data values range from 0 to 100.

Lineage

Firstly, layers of local relief were created using 3 by 3, 5 by 5, 7 by 7, 9 by 9, 11 by 11, and 13 by 13 pixel-windows. Then a local relief average layer was created from the above layers. Finally, the rocky layer was created from the averaged local relief layer, which was calculated using the following functions: y = 100 when x > 500; y = (x-200)/3 when 500 >= x >= 200; y = 0 when x < 200; where x is relief_ave layer and y is the resultant rocky value (between 0 and 100).
