These Landsat 8 composites are made from Level L1T orthorectified scenes, using the
computed top-of-atmosphere (TOA) reflectance. See Chander et al.
(2009)
for details on the TOA computation.
As of May 1, 2017, the USGS is no longer producing Pre-Collection Landsat, and therefore this collection is complete. Please switch to a Collection 1-based dataset. See this documentation page for more information.
The Enhanced Vegetation Index (EVI) is generated from the
Near-IR, Red and Blue bands of each scene, and ranges in value from
-1.0 to 1.0. See
Huete et al. (2002)
for details.
These composites are created from
all the scenes in
each 32-day period beginning from the first day of the year and
continuing to the 352nd day of the year. The last composite of the
year, beginning on day 353, will overlap the first composite of the
following year by 20 days. All the images from each 32-day period are
included in the composite, with the most recent pixel as the composite value.
