[Matplotlib-users] retrieve a value at from projected data at a specific lon/lat?

[Mike B. <mb...@gi...>]

Hello,

Is there a way to get the data value at a specific longitude/latitude
from an array that has been projected and smoothed with basemap and
transform_scalar to a higher grid density?

My original data is a global lat,lon array (73,144) that I process by
hemisphere with a polar centered 'laea' projection (limited to 15
degrees in each hemisphere). The data is also
run through transform_scalar w/ say the result array being (180,360).
What I want is a way to either get the data value at lon=x,lat=y from
this array or a way to map the indices (180,360) such that
I know index i,j is bound by a set of latitudes and longitudes.

Thanks for any suggestions.

Mike
