Landsat 9 Project Scientist Jeff Masek discusses the ways Landsat data is used and how important it is to have high quality data.
How can I find the acquisition time for a Landsat scene?
Landsat descending (daytime) acquisitions run from north to south; they cross the equator between 10:00 am and 10:25 am local time on each pass to provide maximum illumination.
The exact acquisition start and stop times for each scene are listed in the metadata file that is included in the Landsat Level-1 product, and also displayed on EarthExplorer, GloVis and the LandsatLook Viewer. Landsat data acquisition times are expressed in Greenwich Mean Time (GMT).

Can Landsat satellite acquisition requests be made for a specific date and location?
The Landsat 8 and Landsat 9 satellites together acquire approximately 1,500 scenes daily. These scenes are available for download within 6 hours of acquisition. Landsat satellite acquisitions are managed as a system, known as a satellite constellation. Long-Term Acquisition Plans (LTAPs) direct and optimize the daily acquisitions of each active Landsat satellite. Special requests for future...
What are the acquisition schedules for the Landsat satellites?
The Landsat 8 and Landsat 9 satellites orbit the Earth at an altitude of 705 kilometers (438 miles) in a 185-kilometer (115-mile) swath, moving from north to south over the sunlit side of the Earth in a sun synchronous orbit, following the Worldwide Reference System (WRS-2) . Each satellite makes a complete orbit every 99 minutes, completes about 14 full orbits each day, and crosses every point on...
How do I search for and download ascending (nighttime) Landsat scenes?
Ascending (nighttime) WRS-2 Path/Row numbers are different from descending (daytime) Path/Rows. Cloud cover values for Landsat night scenes will always be zero. If you know the daytime path/row or coordinates and want to know the nighttime path/row, use the WRS-2 Path/Row to Latitude/Longitude Converter . Use EarthExplorer to search using path/row or coordinates: Access EarthExplorer. On the...
How do I search for and download Landsat data?
Landsat data products held in the USGS archives can be searched and downloaded at no charge from a variety of sources. Visit Landsat Data Access for information about how Landsat data products can be downloaded individually or in bulk. Landsat imagery not found in the USGS archive might have been collected by one of the USGS International Cooperator ground stations, each of which are the primary...
Are there any restrictions on the use or redistribution of Landsat data?
There are no restrictions on Landsat data downloaded from the USGS; it can be used or redistributed as desired. We do request that you include a statement of the data source when citing, copying, or reprinting USGS Landsat data or images. Details are on the EROS Data Citation page.

What are the best Landsat spectral bands for use in my research?
The Spectral Characteristics Viewer is an interactive tool that can be used to visualize how the bands, or channels, of different satellite sensors measure the intensity of the many wavelengths (colors) of light. This is also known as the relative spectral response (RSR). By overlaying the spectral curves from different features (spectra), one can determine which bands of the selected sensor will...
How does data from Sentinel-2A’s MultiSpectral Instrument compare to Landsat data?
The Sentinel-2A MultiSpectral Instrument (MSI) data has spectral bands very similar to Landsat 8 and 9 (excluding the thermal bands of Thermal Infrared Sensor (TIRS)). All Sentinel-2 data are freely available from the Copernicus Open Access Hub; therefore, users are encouraged to download the data via https://scihub.copernicus.eu/ .

This is the third video in a series describing the new U.S. Geological Survey (USGS) Landsat Collection 1 inventory structure. Collection 1 required the reprocessing of all archived Landsat data to achieve radiometric and geometric consistency of Level-1 products through time and across all Landsat sensors.
