I'm working with some MODIS satellite imagery. MODIS data includes a quality flag mask. For the particular dataset I'm working with, this is a two dimensional unsigned 16 bit integer array. The quality flags are stored as one or more bits in each integer value:

I've written a cython wrapper around some C++ functions that use the the std::bitset datatype to read bits in the MODIS cloud mask (the MYD035/MOD035 files). Email me if you'd like a copy with a simple demo, it wouldn't be hard to adapt to the quality flag mask -- regards, Phil Austin
