Landsat 8 Collection 1 Tier 1
calibrated top-of-atmosphere (TOA) reflectance.
Calibration coefficients are extracted from the image metadata.
See Chander et al. (2009)
for details on the TOA computation.
These composites are created from
all the scenes in
each annual period beginning from the first day of the year and
continuing to the last day of the year. All the images from each year
are included in the composite, with the greenest pixel as the composite value, where
the greenest pixel means the pixel with the highest value of
the Normalized Difference Vegetation Index (NDVI).
The pixel with the highest value of the Normalized Difference Vegetation Index (NDVI) for the year covered by the image.
