Landsat Data Access

You are here

There are a number of ways to access data held in the USGS archives. There are no restrictions on Landsat data downloaded from USGS EROS, and it can be used or redistributed as desired. However, a statement of the data source when citing, copying, or reprinting USGS Landsat data or images is requested. Details can be found on the EROS Data Citation page.

Landsat Level-1 Data Products

Landsat Level-1 data products are available for immediate download. Before downloading Landsat products, it is important to understand that a number of files will be included, and how the individual band files work together in image processing software to create a final image. Please see these pages for more details:

Landsat Collection 1 Level-1 Data Products

All Landsat 4-5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 8 Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS)  Collection 1 Level-1 data products held in the USGS archives can be searched by using:

EarthExplorer – Provides a graphical user interface to define areas of interest (AOI) by place name, address, zip code or creating an AOI on the interactive map. Queries can be applied to multiple collections simultaneously.  (Landsat Collection 1 Level-1 datasets are listed under the Landsat section on the Data Set tab. User login required to download data and/or metadata.)

GloVis – A next-generation global visualization viewer provides access to select datasets within the USGS remote sensing archive.

LandsatLook Viewer – Allows rapid online viewing and access to the USGS Landsat Pre-Collection image archives.

Landsat Pre-Collection Level-1 Data Products

EarthExplorer –  The Landsat 1-5 MSS Pre-Collection dataset will remain available on EarthExplorer until the dataset is processed into the Collection 1 archive structure, which is planned for late 2017.

Landsat Data File List Ordering Tool

The File List Ordering Tool allows text file, metadata export, and scene list uploads for more effective downloading and/or ordering for all datasets visible on EarthExplorer.  User login required.

Bulk Download Application (BDA)

The Bulk Download Application (BDA) is an easy-to-use tool for downloading large quantities of data visible on EarthExplorer. Once scenes are added to a Bulk Order via Earth Explorer, the Bulk Download Application can be used to automatically retrieve them with little to no user interaction. The application will automatically iterate through the scene list and download each until all have been processed. It allows the user to re-arrange, pause, skip, and resume downloads at will.
 

Landsat Level-2 Science Data Products

Surface Reflectance and other Level-2 science data products for Landsat Collection 1 data products can be requested through the pages described below.

USGS Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) On Demand Interface – Allows text file (*.txt) uploads of Landsat Collection 1 Level-1 or MODIS scenes, and the selection of Level-2 Landsat data products (such as top-of-atmosphere (TOA) reflectance, surface reflectance (SR), SR-based spectral indices (NDVI, NDMI, NBR, SAVI, EVI), as well as customizable output options and output product statistics plotting.

Orders submitted through ESPA are processed within 2-5 days, depending on the size of the order. Email notifications are sent after the order is placed, and also after the data is processed and ready to download.

ESPA Application Programming Interface (API) – enables users to write their own clients to interact with all bulk ordering and downloading capabilities.

EarthExplorer – Allows ordering of only surface reflectance (SR) data products. Requests originating from EarthExplorer are sent to the ESPA On-Demand interface for processing and data delivery. Note: Data processed by ESPA are not accessible using the EarthExplorer interface or Bulk Download Application (BDA).

Bulk Download Options for Level-2 Science Data Products

ESPA Application Programming Interface (API) – enables users to write their own clients to interact with all bulk ordering and downloading capabilities.

ESPA Bulk Download Client – A python-based tool that retrieves all completed scenes per user and/or order and places them into a target directory.

About

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.

Landsat Updates

The Landsat Update is an informal communication tool, prepared periodically and distributed electronically to USGS Landsat partners, to provide information about Landsat activities and related topics of interest.
