cartopy.io.img_tiles.GoogleTiles#

class cartopy.io.img_tiles.GoogleTiles(desired_tile_form='RGB', style='street', url='https://mts0.google.com/vt/lyrs={style}@177000000&hl=en&src=api&x={x}&y={y}&z={z}&s=G', cache=False)[source]#
Parameters:

  • desired_tile_form (str, optional) – The desired format of the tile (defaults to “RGB”).

  • style (str, optional) – The style for the Google Maps tiles. One of ‘street’, ‘satellite’, ‘terrain’, and ‘only_streets’. Defaults to ‘street’.

  • url (str, optional) – URL pointing to a tile source and containing {x}, {y}, and {z}. Such as: 'https://server.arcgisonline.com/ArcGIS/rest/services/World_Shaded_Relief/MapServer/tile/{z}/{y}/{x}.jpg'

  • 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.
