  Description:
    Abstract:
      These data were collected by the SHOALS (Scanning
      Hydrographic Operational Airborne Lidar Survey) system
      which consists of an airborne laser transmitter/receiver
      capable of measuring 400 soundings per second. The
      system operates from a deHavilland DHC-6 Twin Otter
      flying at altitudes between 200 and 400 meters with a
      ground speed of about 100 knots. The SHOALS system
      also includes a ground-based data processing system
      for calculating acurate horizontal position and water
      depth.
      Lidar is an acronym for LIght Detection And Ranging. The
      system operates by emitting a pulse of light that travels
      from
      an airborne platform to the water surface where a small
      portion of the laser energy is backscattered to the
      airborne
      receiver. The remaining energy at the water's surface
      propogates through the water column and reflects off the
      sea bottom and back to the airborne detector. The time
      difference between the surface return and the bottom
      return corresponds to water depth. The maximum depth
      the system is able to sense is related to the complex
      interaction of radiance of bottom material, incident sun
      angle and intensity, and the type and quantity of organics
      or sediments in the water column. As a rule-of-thumb, the
      SHOALS system should be capable of sensing bottom to
      depths equal to two or three times the Secchi depth.
    Purpose:
      The purpose of the Kauai survey was to gather bathymetry
      around the island to determine general conditions and to
      provide data for storm run-up models.
