Landsat Science Data Product Access

You are here

Processing for Landsat Surface Reflectance and other Landsat science data products can be requested through the following pages:

USGS Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) On-Demand Interface

To begin the order, upload a text file (*.txt) listing one Landsat Level-1 product or one MODIS granuale identifier on each line. Archived Landsat 4-5 TM scenes acquired from August 1982 to May 2012; Landsat 8 and Landsat 7 scenes within one week of acquisition can be processed. The Surface Reflectance Caveats and Constraints section provides more information on these and other restrictions.

After uploading the scene list text file, a number of options can be selected, including:

  • Source products (Original input Level-1 product or metadata)
  • Top-of-atmosphere (TOA) reflectance, surface reflectance (SR), or brightness temperature (BT) products
  • SR-based spectral indices (NDVI, EVI, SAVI, MSAVI, NDMI, NBR, NBR2)
  • Customizable output options: data format, reprojection, modifying the image extents, and pixel resizing
  • Intercomparison and output product statistics plotting

All orders submitted through ESPA are processed within 1-3 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.

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). Please refer to the ESPA On-Demand User Guide for more information.
 

Bulk Download Options for Landsat 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.
