plot_osm_basemap

Latitude-longitude range to be plotted as returned from
get_xylims()

xylims

Name of plot file; default=NULL plots to screen device (low
quality and likely slow)

filename

Width of graphics file (in px; default 480).

width

Data frame returned by osm_structures() used here to
specify background colour of plot; if 'structs=NULL', the colour is specified
by 'bg'

structures

Background colour of map (default = 'gray20' only if structs not
given)

Type of graphic device to print to. For example, 'png'
(default), 'jpeg', 'png', or 'tiff'

graphic.device

Other parameters to be passed to graphic device (such as width and
height; see ?png, for example, for details)

Generates a base OSM plot ready for polygon, line, and point objects to be
overlain with add_osm_objects(). NOTE: Graphics files must be closed after
finishing map with dev.off() or graphics.off(). Unless specified, height of
graphics device is automatically calculated in proportion to the given width
according to the aspect ratio of the bounding box.

Produces customisable images of OpenStreetMap data.  Extracts OpenStreetMap data for specified key-value pairs (e.g.  key="building") using the overpass API. Different OSM objects can be plotted in different colours using the function add_osm_objects().  The function group_osm_objects() enables customised highlighting of selected regions using different graphical schemes designed to contrast with surrounding backgrounds.
