Exporting maps as HTML¶

You can either click the camera icon on toolbar to export maps or use the following script.

In [7]:

import os

import os

In [8]:

download_dir = os.path.join(os.path.expanduser('~'), 'Downloads')
if not os.path.exists(download_dir):
    os.makedirs(download_dir)
html_file = os.path.join(download_dir, 'my_map.html')

download_dir = os.path.join(os.path.expanduser('~'), 'Downloads') if not os.path.exists(download_dir): os.makedirs(download_dir) html_file = os.path.join(download_dir, 'my_map.html')

In [9]:

Map.to_html(outfile=html_file, title='My Map', width='100%', height='880px')

Map.to_html(outfile=html_file, title='My Map', width='100%', height='880px')

Exporting maps as PNG/JPG¶

Make sure you click the fullscreen button on the map to maximum the map.

In [10]:

png_file = os.path.join(download_dir, 'my_map.png')

png_file = os.path.join(download_dir, 'my_map.png')

In [11]:

Map.to_image(outfile=png_file, monitor=1)

Map.to_image(outfile=png_file, monitor=1)
