π§ Methodology & System Overview
This dashboard presents an integrated AI-driven system for the detection, quantification, and forecasting of methane emissions across Canada, using a hybrid, multi-source data fusion approach. The system combines satellite imagery, geospatial overlays, and temporal modeling to identify current hotspots and predict future methane concentrations.
π Data Sources
- Satellite Data (Sentinel-5P TROPOMI): Monthly gridded CHβ (methane) concentration data collected between 2019 and 2024, processed at tile level resolution.
- Industrial Proximity & Land Use: Features derived from OpenStreetMap and provincial industrial registries, including distances to petroleum, mining, and agricultural zones.
- Environmental & Geographic Features: Data on elevation, land cover, and population density integrated using Google Earth Engine to enhance contextual learning.
Note: These datasets are not streamed in real time. They are periodically retrieved and processed in batch mode.
π§ Modeling Approach
- Hotspot Detection: Anomaly detection using quantile-based thresholds and spatial clustering to flag high CHβ zones.
- Forecasting: Supervised regression models (e.g., XGBoost, LSTM variants) trained to predict monthly methane concentration up to 3 years ahead.
- Feature Fusion: Spatial and temporal features are fused into structured tile-level datasets for localized and global prediction.
βοΈ System Architecture
- Preprocessing: Conducted in Google Earth Engine, with data exported for downstream modeling.
- Model Training: Performed offline using Python (scikit-learn, TensorFlow), with temporal validation splits.
- Dashboard Integration: Visualizations created using Plotly, Folium, and Leaflet.
- Deployment: This dashboard is a static web application; real-time data integration is not implemented.
