get_stadia_map: Wrapper around ggmap::get_stadiamap()

In Ostluft/rOstluft.plot: Ploting air quality data

Wrapper around ggmap::get_stadiamap()

Description

The functions get_googlemap() and get_stadia_map() tries to harmonize the calls to ggmap(). The objective is to get interchangeable functions with sensible defaults. For example automatic calculation of the zoom. The function bbox_lv95() generates a bbox object compatible with both functions.

Usage

get_stadia_map(
  bbox,
  maptype = "stamen_terrain",
  width = 640,
  zoom = "auto",
  color = "bw",
  ...
)

Arguments

bbox	list with items left, bottom, right and top as WSG84 coordinates. Additional width in meters if zoom = "auto". Use bbox_lv95() to create a compatible bounding box list
maptype	stamen_terrain, stamen_toner, stamen_toner_lite, stamen_watercolor, stamen_terrain_background, stamen_toner_background, stamen_terrain_lines, stamen_terrain_labels, stamen_toner_lines, stamen_toner_labels.
width	of resulting map in pixels.
zoom	zoomlevel from 0 to 18 or "auto"
color	color or black-and-white. Changed default to "bw"
...	forwarded to ggmap::get_stadiamap()

Value

a ggmap object (a classed raster object with a bounding box attribute)
