Landsat Path/Row

The Landsat 8 satellite orbits the the Earth in a sun-synchronous, near-polar orbit, at an altitude of 705 km (438 mi), inclined at 98.2 degrees, and circles the Earth every 99 minutes. The satellite has a 16-day repeat cycle with an equatorial crossing time: 10:00 a.m. +/- 15 minutes.

Landsat satellites image the entire Earth every 16 days in an 8-day offset. Landsat 7 acquires data in descending (daytime) node, while Landsat 8 acquires data in both descending and occasional ascending (nighttime) node. 

Row refers to the latitudinal center line of a frame of imagery. As the satellite moves along its path, the observatory instruments are continuously scanning the terrain below.  These will be squares centered on the orbital path, but tilted clockwise when viewed on the UTM projection used for the distributed data.
