Learning Objectives: 
  • Compare and contrast common sensors by spatial resolution, spectral sensitivity, ground coverage, and temporal resolution (e.g., AVHRR, MODIS [intermediate resolution ~500 m, high temporal] Landsat, commercial high resolution [Ikonos and Quickbird]
  • Evaluate the advantages and disadvantages of acoustic remote sensing versus airborne or satellite remote sensing for seafloor mapping
  • Select the most appropriate remotely sensed data source for a given analytical task, study area, budget, and availability
  • Differentiate between “push-broom” and “cross-track” scanning technologies
  • Evaluate the advantages and disadvantages of airborne remote sensing versus satellite remote sensing
  • Differentiate between “active” and “passive” sensors, citing examples of each
  • Explain the principle of multibeam bathymetric mapping
