Are all acquired Landsat scenes held in the USGS Landsat archive?

The USGS archive contains data acquired by the Landsat satellites from 1972 to present.

Data is downlinked to various ground stations around the world. While each ground station in the International Cooperator (IC) network is the primary source for distributing the captured data in their area, copies of the data have also been made available to the USGS to place in the Landsat archive for distribution via EarthExplorer, GloVis, and the LandsatLook Viewer.

Historical data not found in the USGS archive might be available from the ground station that collected the data. Go to the Landsat International Ground Station Network for contact information and coverage maps.

In 2010, the Landsat Global Archive Consolidation (LGAC) effort was created to consolidate the Landsat data archives of all international ground stations, make the data more accessible to the global Landsat community, and significantly increase the frequency of observations over a given area of interest to improve scientific uses such as change detection and analysis.

What are the acquisition schedules for the Landsat satellites?

The Landsat 7 and Landsat 8 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 World Reference System (WRS-2) . Each satellite makes a complete orbit every 99 minutes, completes about 14...

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...

What is the naming convention for Landsat Collections Level-1 scenes?

The Landsat Collection 1 Level-1 product identifier includes the Collection processing levels, processing date, collection number, and collection iter category: LXSS_LLLL_PPPRRR_YYYYMMDD_yyyymmdd_CC_TX Where: L = Landsat X = Sensor (“C”=OLI/TIRS combined, “O”=OLI-only, “T”=TIRS-only, “E”=ETM+, “T”=“TM, “M”=MSS) SS = Satellite (”07”=Landsat 7, “08...

Can Landsat satellite acquisition requests be made for a specific date and location?

Data acquisition requests are not available to the public. The Landsat 8 and Landsat 7 satellites each acquire data on a continual basis in accordance with their respective Long Term Acquisitions Plans. The Landsat Acquisitions page has calendars and information about daily schedules. Learn more: Landsat 8 Long Term Acquisitions Plan Landsat 7...

How do I open Landsat satellite data files?

Many image processing programs (ERDAS IMAGINE®, PCI Geomatica®, ENVI®, IDRISI®, etc.)* can import a variety of image formats, including the GeoTIFF files of Landsat data. Free Multispec software that is included with the USGS lesson plan Tracking Change Over Time can be used for limited spectral analysis. To view Landsat scenes without using...

Tapestry

Soft colors contrast with harsh terrain in southwestern Saudi Arabia, near the border with Yemen. Calming blues and purples seem to collide with an angry orange in this rich tapestry of colors, which are the result of the region’s complex geology. The wild shapes in this busy landscape lie in a region known as the Asharah fault zone.

Expressions in the Desert

In a remote part of the Western Desert in central Egypt, highly eroded plateaus rise from the desert floor. The bright speckles are ancient dry lakes, the salt deposits reflecting brightly. Long ago, water flowed off the plateau, forming the breaches seen on the plateaus’ edges. This desolate land between oases is surrounded by extensive sand dunes.
