Detailed Description

Used to get geographic coordinates from tile keys and vise versa.

Member Function Documentation

static TileKey olp::geo::TileKeyUtils::GeoCoordinatesToTileKey	(	const ITilingScheme &	tiling_scheme,
		const GeoCoordinates &	geo_point,
		const std::uint32_t	level
	)

static

Gets the key of the tile that contains geographic coordinates.

Parameters

[in]	tiling_scheme	The tiling scheme.
[in]	geo_point	The geographic coordinates for which you want to find the container tile key.
[in]	level	The level of the tile.

Returns: The key of the tile that contains the geographic coordinates. If the tile cannot be calculated, an invalid tile is returned.

static std::vector<TileKey> olp::geo::TileKeyUtils::GeoRectangleToTileKeys	(	const ITilingScheme &	tiling_scheme,
		const GeoRectangle &	geo_rectangle,
		const std::uint32_t	level
	)

static

Gets the keys of the tile that overlaps with a geographic rectangle.

Parameters

[in]	tiling_scheme	The tiling scheme.
[in]	geo_rectangle	The rectangle for which to find overlapping tile keys.
[in]	level	The level of the tile key.

Returns: The keys of the tile at the specified level overlapping with the provided geographic rectangle. If the tile cannot be calculated, an empty container is returned.

static TileKey olp::geo::TileKeyUtils::GetAbsoluteSubTileKey	(	const TileKey &	parent,
		const TileKey &	sub_tile
	)

static

Merges the given parent tile key and the child tile key into an absolute tile key.

Parameters

parent	The parent tile key.
sub_tile	The child tile key.

static TileKey olp::geo::TileKeyUtils::GetRelativeSubTileKey	(	const geo::TileKey &	key,
		std::uint32_t	parent_level
	)

static

Gets the tile key that is a relative of a given parent.

Parameters

key	The tile key to convert to.
parent_level	The level of the parent tile. It is expected to be less than or equal to `key.Level()`.
