WorldView-4: High-Resolution Optical Satellite Imagery Archive

WorldView-4 satellite imagery provides panchromatic products with up to 0.31-meter ground sample distance (GSD) resolution and 4-band multispectral products with up to 1.24-meter GSD. The data is processed to various levels, including standard, view-ready, and orthorectified products at resolutions from 0.30 to 0.60 meters. This archive is provided by ESA through NASA's Earthdata platform and was last updated in January 2019.

Use Cases

• Land cover classification based on 4-band multispectral (BLUE, GREEN, RED, NIR1) data.
• Creating detailed base maps based on orthorectified products at 0.30-0.60 meter resolutions.
• Change detection analysis based on the panchromatic archive with 0.31m GSD.
• Generating natural color visualizations based on 3-band pan-sharpened (BLUE, GREEN, RED) products.
• Vegetation analysis based on colored infrared (pan-sharpened GREEN, RED, NIR1) imagery.

Strengths

• Offers very high-resolution panchromatic imagery up to 0.31-meter GSD.
• Provides multispectral data in four bands (BLUE, GREEN, RED, NIR1).
• Includes multiple processing levels, including orthorectified products.

Limitations

• Last updated 2019-01-07 00:00:00; freshness should be verified.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and specific file formats are unknown, which may limit suitability assessment.
