Page Summary
The dataset contains Landsat 4 TM Collection 1 Tier 1 composites created from orthorectified scenes using top-of-atmosphere (TOA) reflectance.
Composites are generated for each 8-day period throughout the year.
The dataset is available from 1982-08-21 to 1993-12-11.
The resolution is 30 meters and includes multiple bands and a quality assessment band.
Landsat data is public domain, but acknowledging the USGS as the data source is recommended.
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.
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
by including a line of text citation such as the example shown below.
