Horizon is a comprehensive mobile application designed to provide critical support during natural disasters and emergencies. By combining real-time disaster tracking, emergency service location, and user profile management, Horizon empowers both individuals seeking assistance and emergency service providers.

• Real-time Disaster Tracking: Monitor nearby natural disasters including wildfires, floods, earthquakes, and more.
• Emergency Services Locator: Find nearby hospitals, shelters, and blood donation centers with distance information.
• SOS Emergency Call: Quick access button to contact emergency services.
• Personal Health Profile: Store critical health information for emergency responders.

• Client Management Dashboard: Track and manage emergency response clients.
• Alert Management System: Receive and respond to emergency alerts in real-time.
• Service Coverage Visualization: View service coverage and gaps on an interactive map.

# Navigate to the mobile app directory
cd Horizon

# Install dependencies
npm install

# Start the development server
npm start

# Navigate to the backend directory
cd backend

# Install dependencies
npm install

# Start the server
node server.js

# Navigate to the streamlit directory
cd streamlit

# Install dependencies
pip install -r requirements.txt

# Run the dashboard
streamlit run app.py

1. Create a .env file in the backend directory with the following variables:

   MONGO_URI=your_mongodb_connection_string
   JWT_SECRET=your_jwt_secret
   

2. Update the API base URL in the mobile app:

   • Open Horizon/app/index.tsx
   • Update the API URLs to point to your backend server

1. Disaster Data Collection: The system aggregates data from multiple sources (EONET, GDACS) to provide comprehensive disaster information.

2. Location Services: When a user opens the app, their location is determined (with permission) to find nearby emergency services and disasters.

3. Emergency Services Mapping: The app identifies nearby hospitals, shelters, and blood donation centers using the OpenStreetMap API.

4. Alert System: Emergency service providers can receive and manage alerts through the admin dashboard.

Horizon was developed during the HackUTA 6 hackathon, held on October 12-13, 2024, at the University of Texas at Arlington. HackUTA is one of North Texas' largest hackathons, offering a 24-hour marathon for students to collaborate and innovate on software projects. (hackuta.org)

During the event, our team focused on addressing the challenges of disaster response and emergency management. Leveraging real-time data from NASA's EONET and GDACS, we aimed to create a tool that could assist both individuals in crisis and the emergency services that support them.

Participating in HackUTA 6 provided us with invaluable experience, mentorship, and the opportunity to bring Horizon from concept to reality within a collaborative and competitive environment.
