Adds a slope algorithm that computes the slope of a raster in degrees from the horizontal. The intended range of output values is from 0 (horizontal) to 90 (vertical).
Since it's possible to convert to percentage slope using raster band math (
b1/90), I didn't bother to include any parameters for controlling wether or not the algorithm outputs degrees or percent slope.The only parameter for the algorithm is
buffer, which follows the hillshade defaults. This can be used to reduce edge artifacts in the computed slope. Users should specify the same buffer for the tile request as they do for the algorithm parameter (which defaults to 3).
