2016 Coastal Lidar Topobathy for Marthas Vineyard and Nantucket Islands

October 4 to November 1, 2016, data collected by Leading Edge Geomatics using a Leica Chiroptera II sensor. The dataset contains 7,030 tiles covering 234 square miles around Marthas Vineyard and Nantucket Islands, Massachusetts. Data is in LAS 1.2 format with classifications for ground, water, bathymetric bottom, and noise points.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and bathymetric bottom points.
• Analyzing seafloor topography and submerged features based on bathymetric bottom classifications.
• Creating digital elevation models (DEMs) integrating land and water surfaces based on ground and water surface points.
• Studiating water column properties and noise filtering based on water column and refracted noise classifications.

Strengths

• Data covers a defined area of 234 square miles with 7,030 individual 500m x 500m tiles.
• Includes specific temporal coverage from October 4 to November 1, 2016.
• Point cloud data is classified into 10 distinct categories, including ground, water surface, and bathymetric bottom.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale processing.
