MODIS 'State_1km' questions


Jr.

Recommended Posts

Hey all,
I'm relatively new to the remote sensing side of the GIS field, so I apologize if this seems a basic question, but I can't seem to wrap my head around how the SDSs are set in a daily MODIS dataset (like MOD10A1 or MOD09GA).  As you approach the poles, the number of times a particular pixel is imaged rises.  My question is, how does this affect the setting of the 'State_1km' SDS flags?  From what I've gathered, they are based off the observation with the highest quality, but do they then apply the same SDS across all the pixels for that day?
