These Landsat 4 TM Collection 1 Tier 1 composites are made from Tier 1 orthorectified scenes, using the
computed top-of-atmosphere (TOA) reflectance.
See Chander et al. (2009)
for details on the TOA computation.
The Normalized Difference Vegetation Index is
generated from the Near-IR and Red bands of each scene as (NIR - Red) /
(NIR + Red), and ranges in value from -1.0 to 1.0.
These composites are created from
all the scenes in each
8-day period beginning from the first day of the year and continuing
to the 360th day of the year. The last composite of the year,
beginning on day 361, will overlap the first composite of the
following year by 3 days. All the images from each 8-day period are
included in the composite, with the most recent pixel as the composite value.
