Integrating data

Six perspectives on the EO-LDAS test site in Gebesee, Germany. From top to bottom, MODIS images at 1 km, 500 km and 250 m resolution acquired on 21 August 2010. From left to right, Formosat-2 images at 8 m resolution acquired on 27 July 2010, 21 August 2010 and 20 October 2010. Note that, in the time series, a number of factors influence the radiances detected by the instrument. On top of physical evolution of the land surface (i.e. crop growth), differences in the Sun angle and atmospheric conditions affect the light received by the sensor. The EO-LDAS system takes into account all these factors in deriving a physically consistent integration of the data.
