NTCombinedTileDataSource


@interface NTCombinedTileDataSource : NTTileDataSource

A tile data source that combines two data sources (usually offline and online) and selects tiles based on zoom level. All requests below specified zoom level are directed to the first data source and all requests at or above specified zoom level are directed to the second data source.
