Crate slippy_map_tiles

Expand description

Abstractions and functions for working with OpenStreetMap (etc.) tiles

§Examples

use slippy_map_tiles::Tile;

let t = Tile::new(6, 35, 23).unwrap();

You cannot create invalid tiles

assert!(Tile::new(0, 3, 3).is_none());

AllSubTilesIterator
AllTilesIterator: Iterates over all the tiles in the world.
AllTilesToZoomIterator: Iterates over all the tiles from 0/0/0 up to, and including, max_zoom.
BBox: A Bounding box
BBoxTilesIterator
LatLon: A single point in the world.
Metatile: Metatiles are NxN tiles
MetatilesIterator: Iterates over all the metatiles in the world.
ModTileMetatile: Metatiles as found by mod_tile, always 8x8
Tile: A single tile.

lat_lon_to_tile: Return the x,y of a tile which has this lat/lon for this zoom level
merc_location_to_tile_coords: Return the x,y of a tile which (for this zoom) has this web mercator 3857 x/y, and then the x,y of the pixel within that image (presuming a 256x256 image)
size_bbox_zoom: How many tiles does this bbox cover at this zoom If there is an overflow for usize, None is returned, if not, a Some(...)
size_bbox_zoom_metatiles: How many metatiles, of this scale, does this bbox cover at this zoom If there is an overflow for usize, None is returned, if not, a Some(...) This is less likely to overflow than size_bbox_zoom because metatiles are larger
