Verification Guide

Verify loans and bonds with satellite imagery

Overview

The Verification workflow allows you to verify sustainability-linked loans and bonds using satellite imagery and ground truth data.

Step-by-Step Process

1. Access Verification Tools

Navigate to:

• Green Lens: ESG visualization and verification
• Verification Demo: Ground truth verification
• Ground Truth: Detailed verification data

2. Upload Loan/Bond Information

Enter or upload:

• Loan details
• Geographic coordinates
• Sustainability claims
• Bond information

3. Satellite Analysis

The system performs:

• NDVI Analysis: Vegetation index calculation
• Land Use Classification: TorchGeo ResNet-50 analysis
• Change Detection: Temporal comparison
• Ground Truth Verification: Satellite vs. claims

4. Review Results

Review verification results:

• NDVI scores and trends
• Land use classifications
• Compliance status
• Risk assessments

5. Generate Reports

Create verification reports:

• PDF export
• Data visualization
• Compliance certificates
• Audit trails

Verification Types

Sustainability-Linked Loans

Verify ESG claims:

• Green project verification
• Environmental impact assessment
• Sustainability metrics tracking

Bond Verification

Verify bond terms:

• Credit rating validation
• Collateral verification
• Compliance checking

Satellite Analysis

NDVI (Normalized Difference Vegetation Index)

Measures vegetation health:

• Range: -1 to +1
• Higher values indicate healthier vegetation
• Temporal tracking for trends

Land Use Classification

Identifies land use types:

• Agricultural
• Forest
• Urban
• Water bodies

Best Practices

1. Accurate Coordinates: Ensure precise geographic data
2. Regular Updates: Schedule periodic verification
3. Document Claims: Maintain detailed documentation
4. Review Results: Carefully review verification outputs

Troubleshooting

Verification fails:

• Check coordinate accuracy
• Verify satellite data availability
• Review input data quality

Unexpected results:

• Review ground truth data
• Check classification accuracy
• Consult verification team

Next Steps

After verification:

• Use results in compliance reports
• Update loan/bond status
• Share verification data
• Export for external systems
