I have 15 annual MOD44B (vegetation continuous field) HDFs for 2000-2014, working in Arcmap 10.2. Each contains several bands. The two I'm concerned with are "percent tree cover" and "quality." The quality layer is an 8-bit integer product, where each bit in a pixel represents one of 8 inputs to the corresponding tree cover pixel. Each bit is '0' is good data and '1' if bad data. How can I determine whether the digital numbers are due to a single 2^x from one 'bad' bit or from multiple ones? For example, a pixel with value 32 could be a single bad data input from the 5th input (2^5 = 32) or could be 4 bad inputs (2^1 + 2^2 + 2^3 + 2^4 = 32).
