These Landsat 4 TM Collection 1 Tier 1 composites are made from Tier 1 orthorectified scenes, using the DN values, representing scaled, calibrated at-sensor radiance.
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.
Landsat datasets are federally created data
and therefore reside in the public domain and may be used, transferred, or reproduced without copyright restriction.
Acknowledgement or credit of the USGS as data source should be provided
