Landsat 8 Collection 1 Tier 1 32-Day Raw Composite

AI-generated Key Takeaways

• The Landsat 8 Collection 1 Tier 1 32-Day Raw Composite provides 32-day composites of Landsat 8 imagery, using the most recent pixel as the composite value.

• The dataset includes spectral bands such as coastal aerosol, blue, green, red, near infrared, shortwave infrared, panchromatic, cirrus, and thermal infrared.

• Data is available from April 7, 2013, to January 1, 2022, and is provided by USGS/Google.

• The dataset is comprised of Tier 1 orthorectified scenes, using Digital Number (DN) values representing scaled, calibrated at-sensor radiance.

• Landsat datasets are in the public domain and can be used without copyright restrictions, but USGS should be acknowledged as the data source.

Description

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 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.
