How to draw a specific country by basemap?

Community matplotlib-users

Hi all,

I'm using the Basemap module in matplotlib, it's great to draw a

world map but for a specific country. Empirically, one can draw its
own country by specifying the lats and longs like this example:

And you can use the method: drawcontries() to draw the country

boundries, but all the countries are in the same colour. Does anyone
know how to highlight a specific country? Thanks in advance.

Hi,

An easy way is to use the data from http://www.gadm.org/ and to plot it with m.readshapefile()

Hi,

  An easy way is to use the data from and to

plot it with m.readshapefile()
Thank you very much. The GDAM database is great.

BTW,  would you like to give some suggestions about how to color the

map, i.e., highlight a specific region?

Thanks,

Eric

Hi,

that would do:

data = m.readshapefile(r’borders\ita_adm1’,‘itaborder’,linewidth=0.5)
italy = data[4]
print dir(italy)

italy.set_facecolors(‘red’)
italy.set_alpha(0.5)

I think at some point you"ll meet the limitations of the method, you might need to use another shapefile-reading module …

Hi,

Adding some extra work in the readshapefile method in your code allows you to play with the region names etc,…

I’ve just made a new tutorial script to show this :
