NOAA Ortho-rectified 4-band Aerial Mosaic of Sacramento, CA from 2022

NOAA's National Geodetic Survey provides a 4-band ortho-rectified mosaic of Sacramento, California. The imagery was acquired on August 3, 2022, using an Applanix Digital Sensor System (DSS) from an airplane. This dataset is a product of the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative.

Use Cases

• Coastal landform classification based on 4-band spectral information.
• Shoreline and beach change detection using ortho-rectified aerial imagery.
• GIS analysis and visualization of urban and natural features in Sacramento.
• Training computer vision models for feature extraction from high-resolution aerial photos.

Strengths

• Imagery is ortho-rectified, which corrects for geometric distortions.
• Data was acquired with a high-resolution sensor to support the final mosaic product.
• Source imagery has a specific acquisition date of August 3, 2022.

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 PDF and HTML, suggesting the primary data may be documentation rather than the raw imagery files.
