cartopy.io.img_tiles.ThunderforestTiles#

class cartopy.io.img_tiles.ThunderforestTiles(apikey, style='landscape', resolution='', cache=False)[source]#

Retrieves tiles from https://www.thunderforest.com.

For a full reference on the styles available please see https://www.thunderforest.com/maps/.

Parameters:

  • apikey (str, required) – The authentication key provided by Thunderforest to query their APIs

  • style (str, optional) – Name of the desired style. Defaults to “landscape”. See https://www.thunderforest.com/maps/ for a full list of styles.

  • resolution (str, optional) – Resolution of the images to return. Defaults to an empty string, standard resolution (256x256). You can also specify “@2x” for high resolution (512x512) tiles.

  • cache (bool or pathlib.Path or str, optional) – To allow offline use, as well as not spam tile providers, Cartopy can create a local cache of previously fetched tiles. The default path is cartopy.config["cache_dir"]. If it is set to True, the default path is used. If it is set to a custom path, then this path is used instead of the default one. If it is set to False, the tiles are downloaded each time.

find_images(target_domain, target_z, start_tile=(0, 0, 0))#

Target domain is a shapely polygon in native coordinates.

tile_bbox(x, y, z, y0_at_north_pole=True)#

The (x0, x1), (y0, y1) bounding box for the given tile position.

Parameters:

  • x (int) – The x tile coordinate in the Google tile numbering system.

  • y (int) – The y tile coordinate in the Google tile numbering system.

  • z (int) – The z tile coordinate in the Google tile numbering system.

  • y0_at_north_pole (bool, optional) – Boolean representing whether the numbering of the y coordinate starts at the north pole (as is the convention for Google tiles) or not (in which case it will start at the south pole, as is the convention for TMS). Defaults to True.

tileextent(x_y_z)#

Return extent tuple (x0,x1,y0,y1) in Mercator coordinates.
