readshapefile fails on std99d00

[nzqo]

I just installed basemap via conda and wanted to run your examples/fillstates.py to plot a map of the US. However, on the following line:

shp_info = m.readshapefile('st99_d00','states',drawbounds=True,
                           linewidth=0.45,color='gray')

I receive the error:

Traceback (most recent call last): File "", line 162, in File "/Users/user/anaconda/lib/python3.5/site-packages/mpl_toolkits/basemap/init.py", line 2124, in readshapefile raise IOError('cannot locate %s.shp'%shapefile) OSError: cannot locate st99_d00.shp

Couldn't find any fix or open issue for this, so sorry if I just didn't see it. Any idea what's going on?

It is a shapefile from the census bureau. Unfortunately, the web address in the comments is outdated. If you can find it, let me know and I can update the documentation.

It's in the example directory (+ the other files with the same prefix).

i am also see the same issue

@GavinMoreYoung As mentioned by @QuLogic, the 'st99_d00' files are part of the basemap examples, and they are located in the examples folder within this repository. They do not come with a standard installation of basemap, so you will need to download them from the repository if you want to use them (and write the appropriate path to them in your script).

收到，会尽快给您回复。

@nzqo The most likely reason for your error is if you have run the example from outside the examples folder. Note that the 'st99_d00' files can be found inside the examples folder, and your snippet is using relative paths (i.e. assuming that you are running this code inside the examples folder).
