EMIT Model - Environmental Monitoring and Intelligence Tool

Title

EMIT Model - Environmental Monitoring and Intelligence Tool (CatBoost Classifier)

---

Overview

The EMIT Model (Environmental Monitoring and Intelligence Tool) is an advanced CatBoost Classifier designed to predict potential mining areas by analyzing environmental data. This tool is a part of the EMiTAL (Environmental Monitoring and Intelligence Tool Algorithm) framework and leverages Remote Sensing, RayCasting, and Polygon Gridding techniques to provide high-precision identification of viable mining zones.

Goal

To support decision-making in mining by providing a robust predictive model that identifies areas with high mining potential based on environmental characteristics. This model benefits regulatory bodies, mining companies, and environmental agencies aiming to balance resource extraction with sustainability.

Framework: EMiTAL

The EMiTAL framework integrates several innovative approaches to enhance prediction accuracy:

• Remote Sensing: Captures large-scale environmental data (e.g., vegetation, soil, and air quality).
• RayCasting and Polygon Gridding: Segments geographic regions into grids, enabling precise targeting.
• Environmental Indicators:
  • NDVI (Normalized Difference Vegetation Index): Measures vegetation health.
  • NDWI (Normalized Difference Water Index): Evaluates water content.
  • NDTI (Normalized Difference Tillage Index): Assesses soil disturbance.
  • Land Elevation: Provides terrain insights.
  • Air Quality Metrics: NO2, PM10, and CO to gauge environmental impact.

Model Pipeline

The model pipeline is built to preprocess and optimize environmental data for classification. Using CatBoost’s native handling of categorical data, the pipeline minimizes preprocessing complexity while ensuring high performance.

• Model Type: CatBoost Classifier
• Objective: Binary classification to predict if a region is suitable for mining (True for viable, False for non-viable).
• Cross-Validation Results:
  • Mean Accuracy: 78.32%
  • Standard Deviation: 4.25%
• Final Accuracy on Test Data: 90.32%
