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

NOAA's Integrated Ocean and Coastal Mapping initiative produced this ortho-rectified mosaic from aerial imagery. The source data was captured in a single day on June 19, 2011, using an Applanix Digital Sensor System. The final mosaic tiles are derived from higher-resolution original photographs.

Use Cases

• Coastal change detection based on ortho-rectified imagery from 2011
• Habitat and land cover classification based on infrared wavelength imagery
• Baseline mapping for coastal engineering projects based on the Mean Lower Low Water datum
• Validation of shoreline models based on high-resolution aerial source data

Strengths

• Imagery was ortho-rectified, correcting for geometric distortions.
• Source data was acquired with a high-resolution Applanix Digital Sensor System.
• Imagery has a precise acquisition date of June 19, 2011.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic/temporal bias inherent to a single-day acquisition in 2011.
