```
public class TerrainTileDataSource
extends TileDataSource
```
A tile data source that loads tiles using a HTTP connection.
The requests are generated using a template scheme, where tags in the baseURL string are replaced with actual values.
The following tags are supported: s, z, zoom, x, y, xflipped, yflipped, quadkey, frame.

For example, if baseURL = "http://tile.openstreetmap.org/{zoom}/{x}/{y}.png" and the requested tile has zoom = 2,
x = 1 and y = 3, then the tile will be loaded from the following URL: "http://tile.openstreetmap.org/2/1/3.png".
