Ortho-rectified Aerial Imagery of Narragansett Bay, RI from 2025

NOAA's National Geodetic Survey produced a 4-band ortho-rectified mosaic of Narragansett Bay, Rhode Island. The source imagery was captured on May 12-13, 2025, using a Phase One Digital Sensor System from an airplane. This dataset is a product of the NOAA Integrated Ocean and Coastal Mapping initiative.

Use Cases

• Coastal change detection and shoreline mapping based on high-resolution aerial imagery.
• Land cover classification and habitat analysis based on the 4-band spectral data.
• Developing and validating computer vision models for geomorphic feature extraction based on ortho-rectified tiles.
• Integrating with other geospatial datasets for coastal planning based on the geographic focus on Narragansett Bay.

Strengths

• Imagery is ortho-rectified, which corrects for sensor tilt and terrain relief.
• Source data was acquired at a higher resolution than the final mosaic, suggesting detailed source material.
• Data has a specific and recent acquisition date range of 2025-05-12 to 2025-05-13.

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.
• Available file formats are listed as PDF and HTML, which may not be the primary data formats for the imagery itself.
