Creates a shadow band, with output 1 where pixels are illumunated 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. |
