Landsat Path Row for Nigeria

 The Landsat 8 or Landsat 9 satellite acquires or records images across the earth in 'scenes'. Each scene covers a square of about 185km by 185km (i.e. 115miles by 115miles). A scene is defined by Path and Row, the Path number is always given first, followed by the Row number.

This Path Row helps in defining the Landsat download scene in EarthExplorer. This Path Row can be accessed on the USGS web page in both shapefile or kml formats. The Path Row are described by the World Reference System (WRS) which is a global notation used in cataloging Landsat data. Landsat satellites 1, 2 and 3 followed WRS-1, and Landsat satellites 4,5,7, 8 and 9 follow WRS-2.

There are different Path Row numbers for Landsat satellite image acquired during the nighttime and daytime as seen below;-

Ascending (nighttime) Path Row

Descending (daytime) Path Row

Take note of the Path Row numbers for Nigeria (or your country) and anytime you have a project the requires you to make use of Landsat data, you can easily refer to the Path Row number map to get idea of the scene coverage on your study area.
