GEOSAT-2 Satellite Imagery Archive with 0.4-Meter Resolution

ESA's GEOSAT-2 archive provides high-resolution optical satellite imagery products. Available products include pan-sharpened, panchromatic, multispectral, and bundled image types at processing levels L1B, L1C, and AI-enhanced L1D with resolutions down to 0.4 meters. The imagery is delivered in GeoTIFF or JPEG-2000 format.

Use Cases

• Land cover classification using multispectral bands (R, G, B, NI) from the 4-band multispectral product.
• High-resolution feature detection and mapping using the 0.4-meter pan-sharpened L1D product.
• Stereo photogrammetry and 3D modeling using the stereo pair product from different acquisition viewpoints.
• Change detection analysis by comparing panchromatic or pan-sharpened images from the full archive over time.
• Radiometric analysis for specific spectral bands using the coregistered multispectral product, avoiding pan-sharpened data as noted.

Strengths

• Offers very high spatial resolution down to 0.4 meters for pan-sharpened L1D products.
• Provides multiple product types (pan-sharpened, panchromatic, multispectral, bundle, stereo) for different analytical needs.
• Includes AI-enhanced super-resolution products (L1D) to increase image detail.

Limitations

• Specific row/column counts, spatial coverage, and temporal range for the archive are not provided.
• Pan-sharpened products do not preserve all spectral features and are not suitable for radiometric purposes.
• Imagery of conflict areas is restricted per ESA policy, limiting global coverage.
