NOAA Coastal Orthoimagery of Maine with Infrared and Tidal Data

NOAA's Integrated Ocean and Coastal Mapping initiative produced orthorectified mosaic image tiles for coastal Maine. The dataset includes true color (RGB) and infrared (IR) imagery for Cutts Island, Penobscot, and Reversing Falls, captured from June 5 to 21, 2011, with a ground sample distance of 0.50 meters per pixel. Imagery is provided in TIFF format with associated metadata and browse graphics.

Use Cases

• Analyzing intertidal land cover using infrared bands and mean lower low water (MLLW) imagery.
• Creating base maps for coastal management with orthorectified RGB tiles.
• Conducting change detection studies by comparing this 2011 imagery with later surveys.
• Validating remote sensing algorithms using the 0.50 m GSD and associated FGDC metadata.

Strengths

• Imagery is orthorectified, correcting for sensor tilt and terrain relief.
• Includes both RGB and infrared spectral bands for the Cutts Island region.
• Provides a specific ground sample distance of 0.50 meters per pixel.
• Source imagery was acquired with an Applanix Digital Sensor System (DSS).

Limitations

• Row count, total size, and specific column names are unknown.
• Conflicting last update dates exist: Data.gov lists 2026-03-05, while NASA Earthdata lists 2011-06 21.
• The Penobscot region files contain RGB imagery only, lacking infrared bands.
