Field Detail

ellipsoid

@JsProperty
public Ellipsoid ellipsoid

Gets the ellipsoid that is tiled by the tiling scheme.

Constructor Detail

TilingScheme

@JsConstructor
public TilingScheme()

A tiling scheme for geometry or imagery on the surface of an ellipsoid. At level-of-detail zero, the coarsest, least-detailed level, the number of tiles is configurable. At level of detail one, each of the level zero tiles has four children, two in each direction. At level of detail two, each of the level one tiles has four children, two in each direction. This continues for as many levels as are present in the geometry or imagery source.
