Python Bokeh – Plot for all Types of Google Maps ( roadmap, satellite, hybrid, terrain)

Last Updated : 03 Jun, 2024

Bokeh is a Python interactive data visualization. It renders its plots using HTML and JavaScript. It targets modern web browsers for presentation providing elegant, concise construction of novel graphics with high-performance interactivity. Bokeh can be used to display Google maps. To use Google maps in Bokeh, we will use the

gmap()

function of the

plotting

class. There are 4 basic types of Google maps –

roadmap, satellite, hybrid, terrain

We need to configure the Google map using

GMapOptions()

function. The

GMapOptions()

function contains the parameter

map_type

. Using this parameter we can determine the map type of the Google map. Assign one of the 4 values to this parameter discussed above.

In order to use these maps we have to :

Import the required libraries and modules :
- gmap from bokeh.plotting
- GMapOptions from bokeh.models
- output_file and show from bokeh.io
Create a file to store our model using output_file().
Configure the Google map using GMapOptions(). During the configuration, assign the desired value to the map_type parameter.
Generate a GoogleMap object using gmap().
Display the Google map using show().

Roadmap :

This displays the default road map view. In this type of map, the terrain is smoothened and the roads are highlighted. It is suited to navigate an area in a vehicle. This is the default map type.

# importing the required modules from bokeh.plotting import gmap from bokeh.models import GMapOptions from bokeh.io import output_file, show  # file to save the model output_file("gfg.html")  # configuring the Google map lat = 30.3165 lng = 78.0322 map_type = "roadmap" zoom = 12 google_map_options = GMapOptions(lat = lat,                                  lng = lng,                                  map_type = map_type,                                  zoom = zoom)  # generating the Google map google_api_key = "" title = "Dehradun" google_map = gmap(google_api_key,                   google_map_options,                   title = title)  # displaying the model show(google_map)

Output :

Satellite :

This displays the Google Earth satellite view. It is the bird-eye view without any sort of graphics.

Output :

Hybrid :

As the name suggests, this displays the combination of road map and satellite map. The satellite map is overlayed with graphics of roads.

Output :

Terrain :

This displays a physical map based on the terrain information.
