Part III: Configure street width pixels

OSMnx uses the highway OSM tag to ascribe street widths, in pixels. You can pass in a dictionary of street widths to override the default values. Any street type that does not appear as a key in the street widths dict falls back onto the default_width value.



In [25]:

    
street_widths = {'footway' : 0.5,
                 'steps' : 0.5,
                 'pedestrian' : 0.5,
                 'path' : 0.5,
                 'track' : 0.5,
                 'service' : 2,
                 'residential' : 3,
                 'primary' : 5,
                 'motorway' : 6}
place = 'sf-custom'
point = (37.793897, -122.402189)
fig, ax = ox.plot_figure_ground(point=point, filename=place, network_type='all', street_widths=street_widths, dpi=dpi)
Image('{}/{}.{}'.format(img_folder, place, extension), height=size, width=size)
