Installing the basemap package in Anaconda

Basemap is the Matplotlib subpackage and one of the most commonly used and convenient tools for geographic data visualization in Python. The traditional Python install packages (PIP Install Basemap or Conda Install Basemap) often report errors and indicate that Python 2.7 Basemap and Python 3.6 conflict (Figure). Although 2.7 is a classic and most of the world’s data is still based on 2.x, it has been officially announced that 2.x is only for maintenance until 2020 and 3.x is the future.

The following is the Windows environment Python 3.x installation of basemap to share, for your reference.
Premise: My computer is configured 64 for Win10, Anaconda 3 (64-bit), Python 3.6.
1. First of all, download Basemap and Pyproj installation files according to your computer configuration and Python version. This website mainly provides Python Extension Packages under unofficial Windows environment
Basemap download address: https://www.lfd.uci.edu/~gohlke/pythonlibs/

Pyproj download address: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyproj


Where, 1.1.0 after basemap represents the version number, cp36 represents python3.6, win represents Windows, and amd64 represents the 64-bit system. Basemap is about 120M, Pyproj is only about 3M.
2. Win +R opens the command prompt window, and the CD command sets the current directory to the folder where the download files are stored (I put it on the desktop) and then hits enter. Note: If you are using Spyder version 3.2 or above, please execute the following installation command on Anaconda Prompt (my_root), following the same steps.
3. Then start installing the two files, starting with Pyproj
PIP install pyproj 1.9.5.1 – cp36 – cp36m – win_amd64. WHL

Note that the full name of the file name and the suffix (.whl) cannot be lost, and the same command will install Basemap after successful installation
PIP install basemap – 1.1.0 – cp36 – cp36m – win_amd64. WHL
An error occurs here
You are using PIP version 9.0.1, however version 9.0.2 is available.
You should consider upgrading via the ‘python -m pip install –upgrade pip’ command.
The installation was successful using the easy_install directive:
, first go to the directory of easy_install such as C:\ProgramData\Anaconda3\Scripts
, then through the directive easy_install.exe PIP ==9.0.2 and finally install successfully.


And then install it

Successfully installing prompts you to install.
4. Then test whether the installation is successful

import numpy as np
import pandas as pd
import xarray as xy
import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap
import os

os.chdir(r'F:\NCEP')
temp = xy.open_dataset('air.mon.mean.v401.nc')
air = temp['air']
T30 = temp.sel(time=slice('1981-01-01', '2010-12-01'))
t_average = T30.groupby('time.year').mean(dim='time')
t = t_average.mean(dim='year')
tmp = t['air']
lon = t['lon'][:]
lat = t['lat'][:]
lon, lat = np.meshgrid(lon, lat)

def plt_map(data):
    m = Basemap(projection='mill', llcrnrlat=-90, urcrnrlat=90, llcrnrlon=-180, urcrnrlon=180,
                lat_ts=30, resolution='c')
    x, y = m(lon, lat)
    plt.xlim(-180, 180)
    plt.figure(figsize=(10, 7))
    m.drawcoastlines()
    m.drawparallels(np.arange(-90., 91., 30.))
    m.drawmeridians(np.arange(0., 361., 30))
    m.drawmapboundary(fill_color='white')
    m.contourf(x, y, data, levels=np.linspace(-25, 30, 56), extend='both')
    plt.colorbar(orientation='horizontal', pad=0.05)
plt_map(tmp)
