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 |
