A GIS-based flood awareness and risk mapping system for Northern Namibia.
# Flood Awareness GIS System
A web-based GIS platform for flood risk mapping and public awareness in Northern Namibia, developed as an academic prototype to support disaster preparedness and early warning systems.
## 🌊 Project Overview
This system provides interactive flood risk visualization using GIS technology, integrating real-time weather data, comprehensive Namibian hydrological data, spatial flood zones, and safe evacuation areas. Designed for the oshana floodplain environment of northern Namibia, it supports community-focused disaster risk reduction through accessible web-based tools with detailed spatial analysis capabilities.
### Key Features
- **Interactive Flood Risk Map**: Visualize flood-prone zones, river buffers, high-ground safe areas, and major Namibian rivers
- **Namibia-Specific GIS Data**: Integrated comprehensive hydrological data including Zambezi, Kunene, Okavango, and Orange river systems
- **Population Centers Mapping**: Display major cities and towns with population data for impact assessment
- **AI-Powered Analysis**: Grok AI integration for intelligent flood risk assessment and disaster management insights
- **Real-time Weather Integration**: Live rainfall, temperature, and humidity data from OpenWeatherMap
- **Safe Zones Database**: Spatially-enabled shelters and evacuation points using Supabase + PostGIS
- **River Monitoring Stations**: Real-time monitoring infrastructure locations for flood early warning
- **Elevation Profiles**: Detailed river elevation data for flood modeling and risk assessment
- **Early Warning Alerts**: Flood alerts with severity classification and population-sensitive prioritization
- **Seasonal Awareness**: Flood season indicators with heightened sensitivity during peak months (Jan-Mar)
- “SMS alert functionality is implemented conceptually on the client for demonstration purposes. In production, message dispatch would be secured using Supabase Edge Functions to protect API credentials.”
