Maximum zoom level for which tiles are available, as in the TileJSON spec. Data from tiles at the maxzoom are used when displaying the map at higher zoom levels.

Minimum tile update interval in milliseconds, which is used to throttle the tile update network requests.

Minimum zoom level for which tiles are available, as in the TileJSON spec.

When loading a map, if PrefetchZoomDelta is set to any number greater than 0, the map will first request a tile at zoom level lower than zoom - delta, but so that the zoom level is multiple of delta, in an attempt to display a full map at lower resolution as quick as possible. It will get clamped at the tile source minimum zoom. The default delta is 4.

Influences the y direction of the tile coordinates. The global-mercator (aka Spherical Mercator) profile is assumed.

A setting to determine whether a source's tiles are cached locally.
