Orthorectified near-infrared and true-color aerial imagery mosaics covering the U.S. coastline from Ocracoke, North Carolina, to Virginia Beach, Virginia. The images were acquired in 2008 by the National Oceanic and Atmospheric Administration's National Geodetic Survey from an aircraft flying at 7,500 feet above ground level. This dataset is part of the Integrated Ocean and Coastal Mapping (IOCM) product suite.
Use Cases
- Coastal land cover classification based on near-infrared spectral information.
- Change detection analysis for shoreline erosion or accretion using orthorectified imagery.
- Creating baseline geospatial maps for coastal habitat studies based on the described aerial mosaic.
- Integrating infrared data with other spectral bands for vegetation health analysis in coastal areas.
Strengths
- Imagery has been orthorectified and mosaiced to produce a seamless dataset.
- Data includes both true-color (RGB) and infrared (IR) bands, with IR acquired using an 850 nm cut-on filter.
- Acquired from a controlled nominal altitude of 7,500 feet above ground level.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- The dataset's primary format is listed as PDF and HTML, which may not be ideal for direct geospatial analysis.
