-## 🔬 Data Science Techniques Applied
-
-This project is fundamentally a **data science and ML engineering challenge**. Here's how we apply data science at every stage:
-
-### 1. Data Collection & Engineering
-**Problem:** Acquiring and processing petabytes of satellite imagery data
-- **ETL Pipelines** - Automated data extraction from APIs (Sentinel Hub, GEE)
-- **Data Validation** - Quality checks on imagery (cloud coverage, missing bands)
-- **Feature Engineering** - Calculate NDVI, EVI, moisture indices from raw spectral bands
-- **Data Versioning** - Track dataset versions for reproducibility (DVC)
-
-### 2. Exploratory Data Analysis
-**Problem:** Understanding patterns in multispectral time-series data
-- **Statistical Analysis** - Distribution of forest vs. non-forest pixels across regions
-- **Correlation Analysis** - Which spectral bands best discriminate forest types
-- **Temporal Patterns** - Seasonal vegetation cycles, deforestation trends
-- **Visualization** - False-color composites, spectral signatures, change matrices
-
-### 3. Model Development
-**Problem:** Training deep learning models on imbalanced, noisy satellite data
-- **Architecture Design** - Custom U-Net variants optimized for satellite imagery
-- **Loss Functions** - Focal loss and Dice loss for handling class imbalance
-- **Regularization** - Dropout, batch normalization, data augmentation
-- **Hyperparameter Tuning** - Optuna/Ray Tune for learning rate, batch size optimization
-- **Cross-validation** - Spatial CV to prevent data leakage across nearby tiles
-
-### 4. Model Evaluation & Selection
-**Problem:** Ensuring models generalize across different forest types and regions
-- **Metrics** - F1-score, IoU, precision-recall curves for segmentation
-- **Ablation Studies** - Impact of different input bands, architectures, training strategies
-- **Error Analysis** - Where and why models fail (edge cases, rare forest types)
-- **Benchmark Testing** - Performance on held-out test sets (Amazon, Congo, Southeast Asia)
-- **Uncertainty Quantification** - Calibration plots, confidence intervals
-
-### 5. Prediction & Inference
-**Problem:** Generating predictions at scale with low latency
-- **Model Optimization** - ONNX conversion, quantization, pruning for speed
-- **Batch Processing** - Parallelize inference across thousands of image tiles
-- **Post-processing** - Morphological operations to smooth predictions
-- **Ensemble Methods** - Combine predictions from multiple models
-- **Confidence Thresholding** - Only alert when model is highly confident
-
-### 6. Time Series Analysis
-**Problem:** Detecting change over time in noisy temporal data
-- **Trend Detection** - CUSUM, Mann-Kendall tests for significant forest loss
-- **Change Point Detection** - Identify exact timing of deforestation events
-- **Forecasting** - ARIMA, Prophet, LSTM for predicting future deforestation risk
-- **Anomaly Detection** - Flag unusual patterns (rapid clearing, irregular shapes)
-
-### 7. Statistical Modeling
-**Problem:** Estimating carbon stocks with uncertainty
-- **Regression** - Random Forest, XGBoost for biomass-to-carbon conversion
-- **Feature Selection** - Which variables best predict carbon density
-- **Uncertainty Propagation** - Bootstrap, Bayesian methods for error bars
-- **Spatial Statistics** - Account for spatial autocorrelation in carbon estimates
-
-### 8. MLOps & Production
-**Problem:** Maintaining model performance in production
-- **Continuous Training** - Retrain models as new labeled data arrives
-- **Model Monitoring** - Track prediction drift, data distribution shifts
-- **A/B Testing** - Compare new model versions against production baseline
-- **Logging & Debugging** - Trace predictions back to input data and model version
-- **Scalability** - Kubernetes autoscaling based on inference load
-
-**Why This is Data Science:**
-This isn't just "analyzing satellite images" - it's building an end-to-end ML system that handles big data, trains neural networks, performs statistical inference, and deploys models to production. The remote sensing aspect is the *domain*, but data science and ML engineering are the *methods*.

-
-monitor = ProtectedAreaMonitor(
- area_name="Amazon Rainforest Reserve",
- bounds=(-3.4653, -62.2159, -3.0653, -61.8159)

-```python
-from climatevision import CarbonVerifier
-
-verifier = CarbonVerifier()
-
-# Analyze project area
-carbon_report = verifier.generate_report(
- project_area=project_polygon,
- baseline_year=2020,
- current_year=2024
-)
-
-print(carbon_report.summary())
-# Output: "Total carbon sequestered: 12,450 tons CO2"

-```
-
-### 3. Research & Analysis
-Analyze deforestation trends across regions:

-## 🚀 What Works Right Now
-
-### 1. Models Module ✅
-- **U-Net**: Semantic segmentation for forest/non-forest classification
-- **Attention U-Net**: Improved segmentation with attention mechanism
-- **Siamese Network**: Change detection between two time periods
-- **Early Fusion Network**: Alternative change detection approach
-
-**Test it**:
-```python
-from climatevision.models import UNet, SiameseNetwork
-import torch
-
-# U-Net for segmentation
-model = UNet(n_channels=13, n_classes=2)
-x = torch.randn(1, 13, 256, 256)
-output = model(x) # Shape: (1, 2, 256, 256)
-
-# Siamese for change detection
-siamese = SiameseNetwork(in_channels=13)
-before = torch.randn(1, 13, 256, 256)
-after = torch.randn(1, 13, 256, 256)
-change_map = siamese.predict_binary(before, after)
-```
-
-### 2. Utilities Module ✅
-
-**Metrics**:
-- IoU, Dice coefficient, pixel accuracy
-- Segmentation metrics (F1, precision, recall)
-- Change detection metrics (confusion matrix, kappa)
-- Custom loss functions (Dice Loss, Focal Loss)
-
-**Visualization**:
-- Satellite image display (RGB, false color)
-- Prediction overlays
-- Change detection maps
-- NDVI calculation and visualization
-- Training history plots
-
-**Geospatial**:
-- Coordinate transformations
-- Area calculations (hectares, carbon loss)
-- Bounding box operations
-- GeoTIFF metadata generation
-- Tile generation for large images
-
-**Test it**:
-```python
-from climatevision.utils import (
- calculate_iou,
- visualize_prediction,
- calculate_carbon_loss
-)
-import numpy as np
-
-# Calculate metrics
-pred = np.array([[0, 1], [1, 1]])
-target = np.array([[0, 1], [1, 0]])
-iou = calculate_iou(pred, target, num_classes=2)
-
-# Estimate carbon loss
-deforestation_ha = 100
-carbon_loss_tons = calculate_carbon_loss(
- deforestation_area_ha=deforestation_ha,
- biomass_density_t_per_ha=150
-)
-```
-
-### 3. Configuration System ✅
