These Landsat 8 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 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 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
by including a line of text citation such as the example shown below.
