When the Merge satellite imagery option is turned on in Advanced Settings you may notice striping in the view. When DecipherAg merges the Landsat 7 satellite image (which is striped) with the Landsat 8 image, the greenness index from one may be higher which causes the striping effect.

This difference in greenness index comes from the two satellites passing over the area at different times, capturing changes to the paddock from on-farm activities. Landsat 7 may pass over earlier in the month than Landsat 8 and, for example, the paddock may have been harvested during that time.
