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

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 :

1. Import the required libraries and modules :
   • gmap from bokeh.plotting
   • GMapOptions from bokeh.models
   • output_file and show from bokeh.io
2. Create a file to store our model using output_file().
3. Configure the Google map using GMapOptions(). During the configuration, assign the desired value to the map_type parameter.
4. Generate a GoogleMap object using gmap().
5. 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.

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.
