Class SMTilesMapProvider

  • All Implemented Interfaces:
    Disposable, MapProvider, ProviderContextAware

    public class SMTilesMapProvider
extends LocalTileProviderBase

    SMTiles map service provider. (SMTiles is a cached file format based on the MBTiles specification extension.)

    SMTilesMapProvider provides the ability to obtain a map service from a local SMTiles file or standard MBTiles file and encapsulates the GIS function associated with the SuperMap iServer map.

    MBTiles is a specification that stores tile map data into the SQLite database and can be quickly used, managed, and shared. The specification is developed by MapBox.
