January 2021 through June 2021 will be a significant transition period for users of Esri’s ArcGIS Online Landsat image services. In order to keep current, and offer the latest and greatest Landsat imagery products, we will be introducing new Landsat image services and retiring existing services. In Q2 2021, we will introduce the new services so that users can begin to migrate existing apps, maps, and workflows accordingly. As of June 2021, the services listed in ArcGIS Online Landsat Services for Retirement will no longer be available.
If you use any of our Landsat services, you will want to continue reading for important notes and details. You may also want to bookmark this post as this will be our primary channel for details and updated information pertaining to the transition.

Landsat Collection 2
In 2016, the USGS reorganized the Landsat archive into a tiered collection management structure. The implementation of “collections” represented a substantial change in the management of the Landsat archive by ensuring consistent quality through time and across all instruments. – more from the USGS
In December 2020, the USGS released Landsat Collection 2, marking the second major reprocessing campaign on the Landsat archive. Collection 2 processing resulted in several data product improvements that harness recent advancements in data processing, algorithm development, and data access and distribution capabilities. – more from the USGS
Changes to ArcGIS Online Landsat Services
In Q2 of 2021, we will be introducing new services comprised of Landsat 8, Collection 2 Level-2 imagery. The new Landsat services will not only include all the quality improvements of Collection 2, they will also provide users with atmospherically corrected and analysis ready imagery with the upgrade from Level-1 to Level-2 products.
Our current Landsat services are primarily comprised of Landsat 8, Collection 1 Level-1 imagery, sourced from the Landsat 8 Registry of Open Data on AWS. This archive has officially been flagged as deprecated and is scheduled to be deleted on July 1, 2021. As a result, all Landsat services listed in the ArcGIS Online Landsat Services for Retirement document have been placed into Mature Support and will be retired in June 2021.
Important Note for ArcGIS Enterprise Users
If you are using ArcGIS Enterprise 10.5 to Enterprise 10.8.1, you may find these Landsat Items within your Enterprise portal. Please note, in June 2021, the underlying data and services will no longer be accessible and the Landsat items listed will be broken. Once the new services are available, we will update this post, and any supporting documentation, with information regarding corresponding replacement items and services. For more information on the lifecycle of Living Atlas content in ArcGIS Enterprise, please see the Living Atlas content life cycles and updates help topic.
Existing ArcGIS Landsat GLS services have not been placed in Mature Support at this time and will continue to be available until such time as we are able to provide a Collection 2 equivalent.
