Historical USACE Dredge Project Polygons for Massachusetts Waters

Polygonal extents document federal dredging projects by the US Army Corps of Engineers along the Massachusetts marine coastline. The dataset includes navigational channels, anchorages, harbors, beaches, and dikes, with records historical to December 16, 1998. It was compiled by the organization SCIOPS.

Use Cases

• Analyze the spatial distribution and historical footprint of dredged navigational channels and anchorages using polygon geometries.
• Link project polygons to detailed USACE project descriptions and maps via the provided hyperlink attributes for archival research.
• Map the historical extent of coastal modifications like beaches and dikes for shoreline change analysis.
• Assess the concentration of federal dredging activity in specific harbors or regions along the Massachusetts coastline.

Strengths

• Includes hyperlinks to authoritative USACE project descriptions, histories, and maps for each feature.
• Covers multiple project types: navigational channels, anchorages, harbors, beaches, and dikes.

Limitations

• Data is temporally stale, with no records after December 1998.
• Specific quantitative metrics like row count, file size, and column details are unknown.
• Spatial coverage is limited to Massachusetts marine waters, not a national scope.
