Landsat U.S. Analysis Ready Data (ARD) products are consistently processed to the highest scientific standards and level of processing required for direct use in monitoring and assessing landscape change. Landsat U.S. ARD significantly reduces the magnitude of data processing, removing the need to download and prepare large amounts of data for time-series investigative analysis.
Collection 2 U.S. ARD
Products created from Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8-9 OLI/TIRS data from 1982 - present.
Previous Landsat U.S. ARD Collections
Landsat U.S. ARD became available after the release of Landsat Collection 1 in 2016, and serve as the foundation for the Earth Resources Observation and Science (EROS) Center Land Change Monitoring, Assessment, and Projection (LCMAP) initiative. The December 2020 release of Landsat Collection 2 products allows for the processing of Landsat U.S. ARD products using Collection 2 inputs.
Landsat U.S. ARD are available for the conterminous United States (CONUS), Alaska and Hawaii using Landsat 8 and Landsat 9 Operational Land Imager/Thermal Infrared Sensor (OLI/TIRS), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 4-5 Thematic Mapper (TM) data.
Landsat 1-5 Multispectral Scanner (MSS) feasibility studies are ongoing and will be shared with the Landsat user community upon their completion.
Global Landsat ARD specifications are in development. Information will be provided when details are available.

U.S. Landsat Analysis Ready Data
The U. S. Geological Survey’s approach to analysis ready dataAnalysis Ready Data (ARD) is a recent concept in Earth observing remote sensing which encompasses many different initiatives by individual imagery providers and collaborative international organizations working towards easing/minimizing data preprocessing required by users. This allows users to spend more time on analysis and less time on downloading, formatting, and ingesting. The U. S. GeologicaAuthorsCody Anderson, Steven Labahn, Dennis Helder, Gregory L.

Analysis ready data: Enabling analysis of the Landsat archiveData that have been processed to allow analysis with a minimum of additional user effort are often referred to as Analysis Ready Data (ARD). The ability to perform large scale Landsat analysis relies on the ability to access observations that are geometrically and radiometrically consistent, and have had non-target features (clouds) and poor quality observations flagged so that they can be excludeAuthorsJohn L.

U.S. Landsat Analysis Ready DataU.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 Level-1 precision and terrain-corrected scAuthors
