Local Installation and Usage

Option 1: Using GitHub Pages (Recommended)

Simply visit the live demo link above - no installation required!

Option 2: Running Locally

1. Clone or Download the Repository

   git clone https://github.com/ThatSINEWAVE/Radiosonde-Data-Analyzer.git
   cd Radiosonde-Data-Analyzer

2. Serve the Files with a Local Server

   Due to browser security restrictions, you need to serve the files through a local web server rather than opening the HTML file directly.

   Using Python:

   # Python 3
   python -m http.server 8000
   
   # Python 2
   python -m SimpleHTTPServer 8000

   Using Node.js:

   npx http-server

   Using PHP:

   php -S localhost:8000

3. Open Your Browser Navigate to http://localhost:8000 (or the port you specified)

4. Load Your Data

   • Click "Select Log Files Folder"
   • Navigate to the folder containing your radiosonde .log files
   • Select the folder (the app will load all .log files in that directory)

How to Use

1. Load Data: Use the folder selection button to load your radiosonde log files
2. Map Navigation:
   • Pan by dragging the map
   • Zoom using mouse wheel or +/- buttons
   • Switch between different map styles using the buttons in the sidebar
3. Data Analysis:
   • Click on individual sondes in the sidebar to toggle their visibility
   • Hover over points on the map to see detailed information
   • Analyze trends across the four different charts
4. Statistics: View overall statistics in the sidebar panel
