GeographicTilingScheme

open external class GeographicTilingScheme(options: GeographicTilingScheme.ConstructorOptions? = definedExternally) : TilingScheme(source)

A tiling scheme for geometry referenced to a simple GeographicProjection where longitude and latitude are directly mapped to X and Y. This projection is commonly known as geographic, equirectangular, equidistant cylindrical, or plate carrée.

Properties

ellipsoid

open external override var ellipsoid: Ellipsoid

Gets the ellipsoid that is tiled by this tiling scheme.

projection

open external override var projection: MapProjection

Gets the map projection used by this tiling scheme.

rectangle

open external override var rectangle: Rectangle

Gets the rectangle, in radians, covered by this tiling scheme.

Functions

getNumberOfXTilesAtLevel

open external override fun getNumberOfXTilesAtLevel(level: Int): Int

Gets the total number of tiles in the X direction at a specified level-of-detail.

getNumberOfYTilesAtLevel

open external override fun getNumberOfYTilesAtLevel(level: Int): Int

Gets the total number of tiles in the Y direction at a specified level-of-detail.

positionToTileXY

open external override fun positionToTileXY(position: Cartographic, level: Int, result: Cartesian2? = definedExternally): Cartesian2

Calculates the tile x, y coordinates of the tile containing a given cartographic position.

rectangleToNativeRectangle

open external override fun rectangleToNativeRectangle(rectangle: Rectangle, result: Rectangle? = definedExternally): Rectangle

Transforms a rectangle specified in geodetic radians to the native coordinate system of this tiling scheme.

tileXYToNativeRectangle

open external override fun tileXYToNativeRectangle(x: Double, y: Double, level: Int, result: Rectangle? = definedExternally): Rectangle

Converts tile x, y coordinates and level to a rectangle expressed in the native coordinates of the tiling scheme.

tileXYToRectangle

open external override fun tileXYToRectangle(x: Double, y: Double, level: Int, result: Rectangle? = definedExternally): Rectangle

Converts tile x, y coordinates and level to a cartographic rectangle in radians.
