Ortho-rectified Near-Infrared Aerial Mosaic of Drummond Island, Michigan (2016)

NOAA NGS ortho-rectified mosaic tiles were created from aerial imagery acquired on 20160920 using an Applanix Digital Sensor System (DSS). The data is a product of the NOAA Integrated Ocean and Coastal Mapping initiative, focusing on the Drummond Island (De Tour Passage) area in Michigan. The original higher-resolution source imagery was processed to support the final mosaic.

Use Cases

• Coastal change detection based on ortho-rectified near-infrared imagery.
• Land cover classification for environmental studies based on aerial mosaic data.
• Supporting nautical charting and coastal mapping initiatives based on the IOCM product description.
• Analyzing vegetation health and water boundaries using near-infrared wavelengths.

Strengths

• Imagery is ortho-rectified, which suggests geometric correction for mapping accuracy.
• Source data was acquired at a higher resolution to support the final mosaic, indicating potential detail.
• Specific acquisition date (20160920) and sensor (Applanix DSS) are documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single aerial survey in 2016.
