• Same day: once the image file is ready on disk, one work day is enough for an experienced 4SM practitioner to obtain a reasonable result out of a 4-bands image.
  • Longer: finishing can take a while, though, depending on
    • the radiometric quality of the image
      • system noise, banding, cross talk, bright target recovery
      • oblique viewing
    • the size and complexity of the scene
      • clouds and shadows
      • floating alien objects, like boats, seaweed mats, foam, etc
      • wind conditions and breaking waves
      • glints and adjacency effect
      • heterogeous water types, and locally foul waters
