[Numpy-discussion] subdivide array

Hello,

I have an array of data for a global grid at 1 degree resolution. It's
filled with 1s and 0s, and it is just a land sea mask (not only, but
as an example). I want to be able to regrid the data to higher or
lower resolutions (i.e. 0.5 or 2 degrees). But if I try to use any
standard interp functions, such as mpl_toolkits.basemap.interp it
fails -- I assume due to the data being binary.

I guess there may be a fairly easy routine to do this?? Does someone
have an example?

Thanks!
