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 held in the USGS archives can be searched on the following pages:
EarthExplorer: http://earthexplorer.usgs.gov – allows geographical searches of data held in the USGS archives
Global Visualization Viewer (GloVis): http://glovis.usgs.gov – a browse-based viewer for USGS Landsat Archive data sets
LandsatLook Viewer: http://landsatlook.usgs.gov - a prototype tool that allows rapid online viewing and access to the USGS Landsat archive
The Level 1 Data Products for many scenes are available for immediate download from the websites listed above; processing requests (order) can be placed for scenes not downloadable, using the same websites. After an order is placed and the data are processed, an email notification is returned with the direct download location. Processing generally takes 1-3 days.
Before downloading Landsat data, 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 RGB color image. Please see these pages for more details:

Surface Reflectance and other high level science data products can be ordered through the following pages:
USGS Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) On Demand Interface (https://espa.cr.usgs.gov/)
To begin the order, upload a text file (*.txt) listing one Landsat Level 1 or MODIS scene identifier (filename) on each line. Scene identifiers can be found in the search results on EarthExplorer (http://earthexplorer.usgs.gov) or GloVis (http://glovis.usgs.gov).
After uploading the scene list text file, a number of options can be selected, including:
All orders submitted through ESPA are processed within 2-5 days. Email notifications are sent after the order is placed, and also after the data is processed and ready to download. *Note: Data requested through ESPA are not accessible using the EarthExplorer interface or Bulk Download Application (BDA).
EarthExplorer allows ordering of only the Surface Reflectance (SR) data product. Requests from EarthExplorer are sent to the ESPA On-Demand interface for processing and data delivery.
