# 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
