This layer represents slope complexity which is derived from a Slope layer calculated from elevation data obtained from the PRISM climate group, distributed by Climate Source. From personal communication with Wayne Gibson, it was "based off of GTOPO30 data, and then Barnes filtered to the desired resolution"

SNAP resampled the 2km elevation product to the 1km model resolution by bilinear interpolation, calculated slope, and derived a boolean (0,1) raster where a value of 1 represents a complex slope and a value of 0 represents a less complex slope. This metric is indicative of the amount topographic relief in a given pixel. The criteria used in reclassification of the slope data are as follows: 1. more complex slope (value=1) = slope >= 1.5 degrees 2. less complex slope (value=0) = slope < 1.5 degrees * this metric was derived from: Duffy, P.A., Epting, J., Graham, J.M., Rupp, T.S., McGuire, A.D., 2007. Analysis of Alaskan Burn Severity Patterns Using Remotely Sensed Data. International Journal of Wildland Fire, 16(3), p.277-284.
