arcgisimage doesn't work

[Jinyin-Hu]

I tried to use arcgisimage to plot a background map, but found it not working any way. And the example/testarcgis.py is also not working. Any help with this? Thanks

matplotlib version: 3.6.2 basemap version: 1.2.2 (same issue with 1.3.8)

these are the print information when runing testarcgis.py

Hi @Jinyin-Hu! Can you recheck that your issue occurs with basemap 1.3.8 and it is not a problem related to the local environments? Your issue is caused by the sunsetting of "ESRI_Imagery_World_2D" in ArcGIS, which used to be the default link used by Basemap.arcgisimage. This default link was changed for basemap 1.3.4 (https://github.com/matplotlib/basemap/pull/548) so that it uses "World_Imagery" instead.

Your traceback shows an URL pointing to "ESRI_Imagery_World_2D", so I would expect that the script was run with a basemap version before 1.3.4.

You can check with the following minimal example:

import sys
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits import basemap
from mpl_toolkits.basemap import Basemap

print("Python version:", sys.version_info)
print("Basemap version:", basemap.__version__)

bmap = Basemap(projection="cyl", resolution="i",
               llcrnrlon=-90, llcrnrlat=30,
               urcrnrlon=-60, urcrnrlat=60)

bmap.arcgisimage(verbose=True)
bmap.drawmeridians(np.linspace(-180, 180, 37),
                   labels=[0, 0, 0, 1], color="y")
bmap.drawparallels(np.linspace(-90, 90, 19),
                   labels=[1, 0, 0, 0], color="y")
plt.savefig("example.png")

In my case I get the following:

Python version: sys.version_info(major=3, minor=11, micro=2, releaselevel='final', serial=0)
Basemap version: 1.3.8

Hi @Jinyin-Hu! Did you have time to check my example?

[Jinyin-Hu]

Hi @molinav, it works when using the same versions of python and basemap as yours. Yeah! thanks so much for your reply. I

Nice to hear it! I am closing this issue then.
