ee.Terrain.hillShadow

Creates a shadow band, with output 1 where pixels are illuminated and 0 where they are shadowed.

Takes as input an elevation band, azimuth and zenith of the light source in degrees, a neighborhood size, and whether or not to apply hysteresis when a shadow appears. Currently, this algorithm only works for Mercator projections, in which light rays are parallel.

Usage	Returns
ee.Terrain.hillShadow(image, azimuth, zenith, neighborhoodSize , hysteresis )	Image

Argument	Type	Details
image	Image	The image to which to apply the shadow algorithm, in which each pixel should represent an elevation in meters.
azimuth	Float	Azimuth in degrees.
zenith	Float	Zenith in degrees.
neighborhoodSize	Integer, default: 0	Neighborhood size.
hysteresis	Boolean, default: false	Use hysteresis. Less physically accurate, but may generate better images.
