IRS-1C and IRS-1D Satellite Imagery Archive

1996 to 2009 imagery from the Indian IRS-1C and IRS-1D satellites, providing panchromatic and multispectral data at varying resolutions. The archive includes PAN (5m), LISS-III (25m), and WiFS (180m) sensor data, which have been radiometrically and ortho corrected. It is provided by the European Space Agency (ESA) through the GAF Imagery products.

Use Cases

• Analyze land cover changes from 1996 to 2009 using the temporal coverage of LISS-III multispectral bands.
• Perform detailed urban or feature mapping with the 5-meter resolution PAN (panchromatic) sensor imagery.
• Conduct broad-scale environmental monitoring over 800 km x 800 km scenes using the WiFS sensor's wide coverage.
• Create orthorectified base maps by utilizing the provided ortho corrected (DN) products for different sensors.

Strengths

• Multi-decade temporal coverage from 1996 to 2009 for two satellite missions.
• Offers three distinct spatial resolutions: 5m (PAN), 25m (LISS-III), and 180m (WiFS).
• Data products are radiometrically and ortho corrected, enhancing analysis readiness.

Limitations

• No public catalog is available; data access requires contacting user support to check readiness.
• For PAN and LISS-III ortho products, users may need to supply their own ground control points and DEM if corrections are unavailable.
• The dataset is temporally stale, with the last update in 2009.
