Landsat 7 and Landsat 9 Pixel Count Comparison
Detailed Description
This graphic displays the pixel count for classifications in nearly cloud-free scenes from the Landsat 7 Extended Science Mission, compared to pixel counts in a corresponding Landsat 9 scene.
Within the CFMask Pixel Quality Assessment (QA_PIXEL) data, reasonable agreement has been found between pixel classifications in clear Landsat 7 and Landsat 9 scenes. Many of the differences were due to data acquisition timing (L7 scene center time: 15:34:19.8050354Z; Landsat 9: 17:01:43.1991100Z), the SLC-off artifact in Landsat 7,and orbit offset. There was stronger disagreement in cloudy scenes.
