2011 NOAA Ortho-rectified Mosaic of Merrimack River and Plum Island Sound, Massachusetts (

A 2011 ortho-rectified mosaic of the Merrimack River and Plum Island Sound in Massachusetts, created by the NOAA Integrated Ocean and Coastal Mapping initiative. The source imagery was acquired on June 19, 2011, using an Applanix Digital Sensor System (DSS). The final mosaic is derived from higher-resolution original images.

Use Cases

• Coastal change detection based on ortho-rectified aerial imagery.
• Land use and land cover classification for coastal Massachusetts.
• Creating base maps for habitat or hydrological modeling in the Merrimack River estuary.
• Assessing shoreline erosion or accretion patterns from high-resolution imagery.

Strengths

• Imagery is ortho-rectified, which corrects for geometric distortions.
• Source data was acquired with a high-resolution Applanix Digital Sensor System (DSS).
• Provides a consistent mosaic view of a specific coastal area from a single day in 2011.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias, being from a single day in 2011.
