Get a Stamen Map

Description

get_stamenmap() accesses a tile server for Stamen Maps and downloads/stitches map tiles/formats a map image. Note that Stamen maps don't cover the entire world.

Usage

get_stamenmap(
  bbox = c(left = -95.80204, bottom = 29.38048, right = -94.92313, top = 30.14344),
  zoom = 10,
  maptype = c("terrain", "terrain-background", "terrain-labels", "terrain-lines",
    "toner", "toner-2010", "toner-2011", "toner-background", "toner-hybrid",
    "toner-labels", "toner-lines", "toner-lite", "watercolor"),
  crop = TRUE,
  messaging = FALSE,
  urlonly = FALSE,
  color = c("color", "bw"),
  force = FALSE,
  where = tempdir(),
  https = FALSE,
  ...
)

Arguments

bbox	a bounding box in the format c(lowerleftlon, lowerleftlat, upperrightlon, upperrightlat).
zoom	a zoom level
maptype	terrain, terrain-background, terrain-labels, terrain-lines, toner, toner-2010, toner-2011, toner-background, toner-hybrid, toner-labels, toner-lines, toner-lite, or watercolor.
crop	crop raw map tiles to specified bounding box. if FALSE, the resulting map will more than cover the bounding box specified.
messaging	turn messaging on/off
urlonly	return url only
color	color or black-and-white (use force = TRUE if you've already downloaded the images)
force	if the map is on file, should a new map be looked up?
where	where should the file drawer be located (without terminating "/")
https	if TRUE, queries an https endpoint so that web traffic between you and the tile server is ecrypted using SSL.
...	...
