[Matplotlib-users] Problem on Basemap gshhs data and the associated is_land function

[Jiali Ma <578...@qq...>]

Thanks for reading my mail.
In basemap toolkit of matplotlib, I found the  Coastline data used is from
the GSHHS (http://www.soest.hawaii.edu/wessel/gshhs/gshhs.html).But I found
it barely satisfying to use.
（For that I am from China,but the 2 most prominent rivers,Yangtze river and
Yellow river are not shown ,and another less important river is shown）
So,here I am asking if there is how I can replace this GSHHS coasline data
with my data?How is GSHHS data formatted?So I'd probably work some way out
to make or find another set of data with the same format.
Thanks again for reading .

Are you specifying a sufficiently high resolution and using the 
drawrivers() method?

I think that trying to put your own data into a form to be used as a 
direct substitute for the built-in data would be very difficult, but you 
can always plot things directly on the map.

Thanks for your reply,your answer is quite useful,drawriver function is easy
to use and it works.
