Google Map Python How To Create Markers

In this Google Map Python article i want to show you How To Create Markers. basically we are

using gmaps library for creating of maps.

Check the previous article on Python Google Map

1: Python Google Map Introduction With gmaps

2: Python Google Map Customizing Width & Height

We can add a layer of markers to a Google map. Each marker represents an individual data point.

import gmaps

gmaps.configure(api_key='AI...')

marker_locations = [
(-34.0, -59.166672),
(-32.23333, -64.433327),
(40.166672, 44.133331),
(51.216671, 5.0833302),
(51.333328, 4.25)
]


fig = gmaps.figure()
markers = gmaps.marker_layer(marker_locations)
fig.add_layer(markers)
fig

import gmaps

gmaps.configure(api_key='AI...')

marker_locations = [

(-34.0, -59.166672),

(-32.23333, -64.433327),

(40.166672, 44.133331),

(51.216671, 5.0833302),

(51.333328, 4.25)

]

fig = gmaps.figure()

markers = gmaps.marker_layer(marker_locations)

fig.add_layer(markers)

fig

We can also attach a pop-up box to each marker. Clicking on the marker will bring up the info

box. The content of the box can be either plain text or html.

import gmaps
gmaps.configure(api_key='AI...')
nuclear_power_plants = [
{'name': 'Atucha', 'location': (-34.0, -59.167), 'active_reactors': 1},
{'name': 'Embalse', 'location': (-32.2333, -64.4333), 'active_reactors': 1},
{'name': 'Armenia', 'location': (40.167, 44.133), 'active_reactors': 1},

{'name': 'Doel', 'location': (51.333, 4.25), 'active_reactors': 4},
{'name': 'Tihange', 'location': (50.517, 5.283), 'active_reactors': 3}
]
plant_locations = [plant['location'] for plant in nuclear_power_plants]
info_box_template = """
<dl>
<dt>Name</dt><dd>{name}</dd>
<dt>Number reactors</dt><dd>{active_reactors}</dd>
</dl>
"""
plant_info = [info_box_template.format(**plant) for plant in nuclear_power_plants]
marker_layer = gmaps.marker_layer(plant_locations, info_box_content=plant_info)
fig = gmaps.figure()
fig.add_layer(marker_layer)

plant_info = [info_box_template.format(**plant) for plant in nuclear_power_plants]

marker_layer = gmaps.marker_layer(plant_locations, info_box_content=plant_info)

fig = gmaps.figure()

fig.add_layer(marker_layer)

Markers are currently limited to the Google maps style drop icon. If you need to draw more complex

shape on maps, use the symbol_layer function. Symbols represent each latitude, longitude pair with

a circle whose color and size you can customize. Let’s, for instance, plot the location of every

Starbuck’s coffee shop in the UK.

import gmaps
import gmaps.datasets

gmaps.configure(api_key='AI..')

df = gmaps.datasets.load_dataset_as_df('starbucks_kfc_uk')
starbucks_df = df[df['chain_name'] == 'starbucks']
starbucks_df = starbucks_df[['latitude', 'longitude']]
starbucks_layer = gmaps.symbol_layer(
starbucks_df, fill_color='green', stroke_color='green', scale=2
)
fig = gmaps.figure()
fig.add_layer(starbucks_layer)
fig

import gmaps

import gmaps.datasets

gmaps.configure(api_key='AI..')

df = gmaps.datasets.load_dataset_as_df('starbucks_kfc_uk')

starbucks_df = df[df['chain_name'] == 'starbucks']

starbucks_df = starbucks_df[['latitude', 'longitude']]

starbucks_layer = gmaps.symbol_layer(

starbucks_df, fill_color='green', stroke_color='green', scale=2

)

fig = gmaps.figure()

fig.add_layer(starbucks_layer)
