🎯 What is the Water Quality Reporting System?

Core Purpose

The system serves as a citizen science platform that enables residents to:

  • Report water quality issues in their neighborhoods

  • Visualize water quality patterns across the city

  • Track improvements in water infrastructure

  • Contribute to community health and safety

Key Features

  • 🗺️ Interactive Mapping: Real-time visualization of water quality reports

  • 📝 Anonymous Reporting: Privacy-focused reporting system

  • 🔷 Voronoi Analysis: Advanced spatial analysis showing water quality zones

  • 📱 Mobile Responsive: Works on all devices

  • 🔄 Real-time Updates: Live data synchronization

🛠️ How It Works

Technology Stack

  • Frontend: HTML5, CSS3, Vanilla JavaScript

  • Mapping: Mapbox GL JS with custom styling

  • Database: Firebase Firestore for real-time data

  • Authentication: Anonymous authentication for privacy

  • Spatial Analysis: Turf.js for advanced geospatial calculations

  • Visualization: Voronoi diagrams for zone analysis

Data Flow

  1. User Reports: Citizens click on map and submit water quality issues

  2. Data Storage: Reports saved to Firebase with location data

  3. Spatial Analysis: Turf.js generates Voronoi zones around reports

  4. Visualization: Map displays both individual reports and quality zones

  5. Real-time Updates: New reports immediately update the visualization

🗺️ Mapping Water Quality Data

Voronoi Zone Analysis

The system uses Voronoi diagrams to create natural boundaries around each water quality report, showing the area of influence for each report. This approach provides:

  • 🎯 Natural Boundaries: Mathematically precise zones

  • 📍 Direct Correlation: Each zone corresponds to one water quality report

  • 🔄 Dynamic Updates: Zones automatically adjust with new reports

  • 📊 Clear Attribution: Easy to see which report influences which area

Visual Indicators

  • 🟢 Green Zones: Areas with good water quality

  • 🟡 Yellow Zones: Areas with moderate water quality concerns

  • 🔴 Red Zones: Areas with poor water quality requiring attention

Interactive Features

  • Click to Report: Users click anywhere on the map to submit reports

  • Zone Exploration: Click on zones to see detailed information

  • View Toggle: Switch between individual reports and zone analysis

  • Mobile Optimization: Touch-friendly interface for mobile devices
