Landsat Missions
The gridlines displayed on SLC-off browse images provides a visual of the image effects caused by the scan line corrector failure aboard Landsat 7 in May 2003.
The numerical scale across the top and bottom represents the width (in 30-meter image pixels) of missing data. The dashed lines indicate the approximate width (in pixels) of expected data gaps in the final product, as seen in Figure 1 below. The area between the two solid lines represents the approximate portion of the scene that contains no missing data.
Figure 1. SLC-off browse showing optional yellow gridlines to indicate expected width of the gap region.
A standard 2-pixel interpolation is applied during Level 1 processing of all SLC-off Landsat 7 imagery. The standard 2-pixel interpolation will still be applied to the rest of the image to make the final Level 1 product.
