Page Summary
-
The dataset consists of Landsat 4 TM Collection 1 Tier 1 8-day raw composites available from 1982-08-21 to 1993-12-11.
-
These composites are created from orthorectified scenes using DN values representing scaled, calibrated at-sensor radiance.
-
Composites are made from all scenes within each 8-day period, using the most recent pixel value.
-
The dataset includes multiple spectral bands (Blue, Green, Red, Near infrared, Shortwave infrared 1 & 2, Thermal Infrared 1) and a QA band at 30 meters resolution.
-
Landsat data is in the public domain, and proper acknowledgement of the USGS as the data source is requested.

Description
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.
