Matplotlib Tutorial 27 - Basemap customization options

In this Matplotlib tutorial, we continue with the Basemap geographic plotting extension. We're going to show some of the customization options available to us.

You are a legend... and not a map legend... a gladiator legend!!! Useful tuts!

Thanks for the great tutorials!
And a tip for other watchers, install Pillow for the last function (bluemarble)

[sreenjaysen]

latitudes are the horizontal lines while longitudes are the vertical lines

[ezio]

line show an error of:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in position 2: invalid continuation byte
the modify that is hint isn't correct!
how i can do?

Hello,
I am using basemap to generate a plot for representing CO2 but i need to produce filled contour map of the different concentration at different locations (Lat and Long). Now for generating those maps i need to interpolate the points and this method can be done by nearest neighbour method (interpolation of co2 points). Unfortunately, python is asking me to install (natgrid) library which is so hectic to install. Can you please give me some suggestion on installing natgrid library i have already tried all options.

[chrislam]

how can I know exactly a location coordination? where could i have that infomation?

Is there anyway to increase resolution on the bluemarble thing? (or get something else with higher resolution?)

[ravikumargogineni]

m =Basemap(projection='mill', llcrnrlat=8, llcrnrlon=67, urcrnrlat=37, urcrnrlon=97, resolution='h')
m.drawcoastlines()
m.drawcountries(linewidth=1)
m.drawstates(color='k')
plt.title('Basic map')
plt.show()

But the states are not showing. It shows plain map. How can I show states also for india map?

Hi, Thank you very much for the tutorial. This is AWESOME!!

I am getting this error when I add m.etopo() line. Do you have any idea why that function is not working? I am using python 3.5


File "C:\Anaconda3\lib\site-packages\mpl_toolkits\basemap\__init__.py", line 4167, in warpimage
np.concatenate((self._bm_lons, self._bm_lons+360), 1)

IndexError: axis 1 out of bounds [0, 1)

[mozarter]

line show an error of:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in position 2: invalid continuation byte

guess some country does not encode as utf-8?

How to get all the country names inside a continent?

[tmattoneill]

After adding the m.counties [with or without a colour] I get a series of errors:

Anyone else get this?

[elmirach]

Everything works fine till I try to " m.plot( xpt, ypt, 'c*', markersize=15)" plot the location of NY or LA on a map. Then I get an error "return plotfunc(self, x, y, *args, **kwargs)
File "C:\...\Python\Python36\lib\site-packages\mpl_toolkits\basemap\__init__.py", line 3285, in plot
self._restore_hold(ax)
File "C:\...\Python36\lib\site-packages\mpl_toolkits\basemap\__init__.py", line 3229, in _restore_hold
ax._hold = self._tmp_hold
AttributeError: can't set attribute" Please somebody help me to solve the problem

[thehornandhoof]

Latitude are parallel to equator (horizontal) and Longitude go vertical (up to down).

Anyways tons of thanks for great tutorials.

[TXfoxie]

I took a resolution of full scale, and OMG it took 5 minutes to load the map.

A little trouble here..
