Lake Charles True Color Coastal Orthoimagery Tiles from NOAA

NOAA's Integrated Ocean and Coastal Mapping initiative produced orthorectified mosaic tiles of Lake Charles, Louisiana. The imagery consists of true color RGB images acquired on November 23, 2009 and March 12, 2010 with a ground sample distance of 0.35 meters per pixel. The National Centers for Environmental Information (NCEI) archives these data.

Use Cases

• Analyzing shoreline erosion or accretion by comparing orthorectified tile features from 2009 and 2010 acquisitions.
• Mapping coastal vegetation or land cover using true color RGB pixel values.
• Assessing urban or industrial development near Lake Charles using the 0.35 m GSD imagery.
• Integrating these ortho-rectified mosaic tiles with other NOAA Coastal Mapping Program data for multi-use coastal support.

Strengths

• High spatial resolution with a ground sample distance of 0.35 meters per pixel.
• Provides temporal comparison from two specific acquisition dates in 2009 and 2010.
• Data are ortho-rectified, reducing geometric distortion for accurate spatial analysis.

Limitations

• Limited temporal coverage, only two days of imagery over a short period.
• Geographic scope is restricted solely to the Lake Charles, Louisiana area.
• Sample data, column information, and file format specifics are unknown.
