Detailed Description

Represents a network source for map tiles; contains information about how to connect to the source and how to retrieve tiles from it.

Implementations of this should be specific to a type of map server such as WMS, WMTS, or TMS, and implement the appropriate methods for retrieiving tiles from those servers.

GenerateTileHash()

virtual size_t tile_map::TileSource::GenerateTileHash ( int32_t  level, int64_t  x, int64_t  y  )

pure virtual

Generates a hash that uniquely identifies the tile from this source at the specified level and coordinates.

Parameters

level	The zoom level
x	The X coordinate
y	The Y coordinate

Returns

A hash identifying the tile

Implemented in tile_map::BingSource, and tile_map::WmtsSource.

GenerateTileUrl()

virtual QString tile_map::TileSource::GenerateTileUrl ( int32_t  level, int64_t  x, int64_t  y  )

pure virtual

Generates an HTTP or HTTPS URL that refers to a map tile from this source at the given level and x and y coordinates.

Parameters

level	The zoom level
x	The x coordinate
y	The y coordinate

Returns

A URL referring to the map tile

Implemented in tile_map::BingSource, and tile_map::WmtsSource.
