500 meters landward topography

1000 meters seaward bathymetry

Plan to cover CONUS oceanfront where there is sand.

Lidar Topography in Shishmaref and Kivalina
  • Data collected by Aerometric via NOAA/NGS contract
  • July and August 2004
  • Multiple collections done. Some two-meter resolution, some one-meter resolution.
  • Classified for bare earth.
  • Will be available on-line
  • Approximately 750 million points

experiment objectives
Experiment Objectives
  • Collect Topographic and Bathymetric information safely and at same temporal scale
  • Provide NOAA Ship Rainier with shoreline and near shore hydrographic data within days of acquisition
  • Test a new concept of survey operations

summary
Summary
  • The Coastal Services Center has coastal topography available for most of CONUS.
  • The shoreline for Alaska has been vectorized from T-sheets where they exist.
  • More information might be obtainable from the T-sheets if we can determine what is needed.
  • Limited high-resolution topography exists, but there is data for Shishmaref and Kivalina
  • Combining technologies can provide a seamless elevation dataset across the land-water interface.
