Constructor & Destructor Documentation

Tile() [1/3]

osmium::geom::Tile::Tile ( uint32_t  zoom, uint32_t  tx, uint32_t  ty  )

inlineexplicitnoexcept

Create a tile with the given zoom level and x and y tile coordinates.

The values are not checked for validity.

Precondition

zoom <= 30 && x < 2^zoom && y < 2^zoom 

Tile() [2/3]

osmium::geom::Tile::Tile ( uint32_t  zoom, const osmium::Location &  location  )

inlineexplicit

Create a tile with the given zoom level that contains the given location.

The values are not checked for validity.

Precondition

location.valid() && zoom <= 30 

Tile() [3/3]

osmium::geom::Tile::Tile ( uint32_t  zoom, const osmium::geom::Coordinates &  coordinates  )

inlineexplicit

Create a tile with the given zoom level that contains the given coordinates in Mercator projection.

The values are not checked for validity.

Precondition

coordinates.valid() && zoom <= 30 

Member Function Documentation

valid()

bool osmium::geom::Tile::valid ( ) const

inlinenoexcept

Check whether this tile is valid. For a tile to be valid the zoom level must be between 0 and 30 and the coordinates must each be between 0 and 2^zoom-1.
