The GIFOV is normally a square patch of the earth's surface, but not always as in the case of MODIS.

Effective Ground-projected Instantaneous-Field-Of-View (EGIFOV):

The EGIFOV is normally a square patch of the earth's surface, but not always as in the case of MODIS.

Normalized Difference Vegitation Index (NDVI):
