WHAT IS IT GOOD FOR?

  • Provided the sea-bottom is actually detected in at least two adequate wavebands,
  • and because of its cost-efficiency,
  • passive multispectral bathymetry modeling products are good anywhere in the world
  • when the high cost of collecting similar data in the field is simply not affordable.
