Niihau Topobathy Lidar Elevation Model from 2021 NOAA Survey

Niihau, Hawaii, is covered by this raster topobathy dataset in GeoTIFF format. The data were created from ground and bathymetric lidar point values collected by Woolpert using a Leica Hawkeye4X system. Data acquisition occurred from September 8, 2021, through September 26, 2021.

Use Cases

• Modeling coastal erosion and inundation based on integrated land and bathymetric elevation data.
• Creating nautical charts and navigation aids based on detailed seafloor topography.
• Analyzing coastal habitat and geomorphology based on high-resolution topobathy raster data.
• Supporting coastal engineering and infrastructure planning based on precise elevation models.

Strengths

• Data collection dates are precisely specified as September 8-26, 2021.
• The dataset integrates both ground (2) and bathymetric point (40) lidar values.
• Data originates from the authoritative NOAA National Geodetic Survey.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
