Plot 3D Surfaces Using Axes3D
Description:
A Python program that uses the Basemap toolkit from mpl_toolkits to create a simple world map with coastlines and country boundaries.
Code Explanation:
● Before running this code, install Basemap and related packages using this command in your terminal:
pip install basemap matplotlib basemap-data-hires
● from mpl_toolkits.basemap import Basemap: Imports the Basemap toolkit from matplotlib.
● plt.figure(...): Initializes a plot with specified size.
● Basemap(projection='cyl', resolution='l'): Sets up the world map with cylindrical projection.
● m.drawcoastlines(): Draws the coastlines of continents.
● m.drawcountries(): Outlines the country boundaries.
● m.drawmapboundary(...): Fills the oceans with light blue color.
● m.fillcontinents(...): Fills the land with green and lakes with blue.
● plt.title(...): Sets the title of the map.
● plt.show(): Displays the final map plot.
Program:
from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
# Create a figure and axis
plt.figure(figsize=(8, 6))
# Create a Basemap instance with cylindrical projection
m = Basemap(projection='cyl', resolution='l')
# Draw coastlines, countries, and boundaries
m.drawcoastlines()
m.drawcountries()
m.drawmapboundary(fill_color='lightblue')
m.fillcontinents(color='lightgreen', lake_color='lightblue')
# Add title
plt.title('World Map using Basemap')
# Show plot
plt.tight_layout()
plt.show()
Output:
