Question:

Why are there light and dark lines across my Landsat image?

Answer:

Memory Effect (ME) is an artifact that can be observed as alternating lighter and darker scans. At various times, ME has been known as "banding" or "bright target recovery". ME is typically seen in imagery from bands 1-4, over large areas following a significant transition in radiant intensity such as at a cloud/desert or snow/water boundary.

About

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
