What are Landsat Collection Tiers?
Landsat Collection Tiers are the inventory structure for Level-1 data products and are based on data quality and level of processing. The tier definition purpose is to support easier identification of suitable scenes for time-series pixel-level analysis, and provide temporary data that are processed immediately upon downlink to be dispensed quickly in emergency response situations with limited calibration.

U.S. Landsat Analysis Ready Data
U.S. Landsat Analysis Ready Data (ARD) are a revolutionary new U.S. Geological Survey science product that allows the Landsat archive to be more accessible and easier to analyze and reduces the amount of time users spend on data processing for monitoring and assessing landscape change. U.S. Landsat ARD are Level-2 products derived from...
Landsat Collections
In 2016, the U.S. Geological Survey reorganized the Landsat archive into a tiered collection structure, which ensures that Landsat Level-1 products provide a consistent archive of known data quality to support time-series analyses and data “stacking” while controlling continuous improvement of the archive and access to all data as they are...

New “Landsat Collections” Help Facilitate Land Change Science
Access to consistent high-quality images to study changes on Earth’s surface is getting easier. The USGS Landsat standard (Level-1) product inventory is now structured by data quality and offers improved calibration. Data designated as Tier 1 provide the highest accuracy and can be reliably used to analyze changes to Earth’s surface over time.
Landsat Eyes Help Guard the World’s Forests
“We’re seeing the loss of forests in many places,” said Matthew Hansen, a professor at the University of Maryland. “Dynamics include increasing tropical deforestation, more frequent and severe boreal forest fires, disease in temperate forests and the commoditization of subtropical forests.”

Landsat Collections: Providing a Stable Environmental Record for Time Series Analysis
This video introduces the new U.S. Geological Survey (USGS) Landsat Collection 1 inventory structure. Collection 1 required the reprocessing of all archived Landsat data to achieve radiometric and geometric consistency of Level-1 products through time and across all Landsat sensors
Landsat Analysis Ready Data (ARD)
The U.S. Geological Survey (USGS) has improved Landsat data quality and usability through the creation of Analysis Ready Data (ARD) for the conterminous United States, Alaska, and Hawaii. Landsat ARD greatly reduces the preparatory work currently required to do time-series analysis for understanding landscape change for operational and science users. Landsat Collections
