Level
Configuration values for a multi-resolution, hierarchical collection of tiles organized into levels of increasing resolution.
Properties
The geographic width and height of tiles in the first level (the lowest resolution) of the level set.
Determines the lowest resolution level number.
Determines how many levels to skip from retrieving texture during tile pyramid subdivision.
The height in pixels of images associated with tiles in the level set, or the number of sample points in the latitudinal direction of elevation tiles associated with the level set.
Tile origin for the level set
Functions
Returns the number of levels closest to the specified resolution, but does not exceed it. May be used to configure level sets where a not to exceed resolution is mandated. The result is correct for this configuration's current firstLevelDelta, tileWidth and tileHeight, and is invalid if any of these values change.
Returns the number of levels necessary to achieve the specified resolution. The result is correct for this configuration's current firstLevelDelta, tileWidth and tileHeight, and is invalid if any of these values change.
