Description
This class is specialized for map tiles that can be downloaded from a web server. This includes all web based map services such as OpenStreetMap, Google Maps, Yahoo Maps and more. This class contains all mechanisms necessary to download tiles.
Some preconfigured network map sources are built-in this library, see ChamplainMapSourceFactory.

champlain_network_tile_source_set_uri_format ()
void champlain_network_tile_source_set_uri_format (ChamplainNetworkTileSource *tile_source,const gchar *uri_format);
A URI format is a URI where x, y and zoom level information have been marked for parsing and insertion. There can be an unlimited number of marked items in a URI format. They are delimited by "#" before and after the variable name. There are 4 defined variable names: X, Y, Z, and TMSY for Y in TMS coordinates.
For example, this is the OpenStreetMap URI format: "http://tile.openstreetmap.org/#Z#/#X#/#Y#.png"
