| getTiles {cartography} | R Documentation |
Get map tiles based on a spatial object extent. Maps can be fetched from various open map servers.
getTiles(
x,
type = "OpenStreetMap",
zoom = NULL,
crop = FALSE,
verbose = FALSE,
apikey = NA,
cachedir = FALSE,
forceDownload = FALSE
)
x |
an sf object, a simple feature collection or a Spatial*DataFrame. |
type |
the tile server from which to get the map. See Details for providers. For other sources use a list: type = list(src = "name of the source" , q = "tiles address", sub = "subdomains", cit = "how to cite the tiles"). See Examples. |
zoom |
the zoom level. If null, it is determined automatically (see Details). |
crop |
TRUE if results should be cropped to the specified x extent, FALSE otherwise. If x is an sf object with one POINT, crop is set to FALSE. |
verbose |
if TRUE, tiles filepaths, zoom level and citation are displayed. |
apikey |
Needed for Thunderforest maps. |
cachedir |
name of a directory used to cache tiles. If TRUE, places a 'tile.cache' folder in the working directory. If FALSE, tiles are not cached. |
forceDownload |
if TRUE, cached tiles are downloaded again. |
Zoom levels are described on the OpenStreetMap wiki:
https://wiki.openstreetmap.org/wiki/Zoom_levels.
