What is the Worldwide Reference System (WRS)?

The Worldwide Reference System (WRS) organizes Landsat imagery into a global grid, providing a consistent, reliable framework for locating, comparing, and analyzing data over time and across sensors.

WRS-1 was the first version of the grid, and it was used to collect imagery from Landsats 1, 2, and 3.

WRS-2 updated the original grid and is used by Landsats 4 through 9. 

Landsat 10 is scheduled to launch in 2031, and will use WRS-3. Details about WRS-3 are being finalized and will be added to the reference pages listed below and on the Landsat 10 website when available.
