<div id="bkmrk-%23-gpx-to-kml-convert"><div>\# GPX to KML Converter</div>  
<div>A web-based tool that converts GPX (GPS Exchange Format) files to KML (Keyhole Markup Language) format for use with Google Earth, Google Maps, and other mapping applications.</div>  
<div>\## Features</div>  
<div>- **File Upload Support**: Drag &amp; drop or click to select GPX files</div><div>- **Complete GPX Parsing**: Handles waypoints, tracks, and routes</div><div>- **KML Generation**: Creates properly formatted KML files with:</div><div>- Placemarks for waypoints</div><div>- LineString paths for tracks and routes</div><div>- Configurable styling (colors, line width)</div><div>- Organized folder structure</div>  
<div>- **Customization Options**:</div><div>- Set custom KML document names</div><div>- Choose track colors (Red, Green, Blue, Yellow, Magenta, Cyan)</div><div>- Adjust line width (1-10px)</div><div>- Toggle waypoints, tracks, and routes individually</div>  
<div>- **User-Friendly Interface**:</div><div>- Real-time file validation</div><div>- Progress tracking during conversion</div><div>- Statistics display (waypoint/track counts)</div><div>- KML preview before download</div><div>- Comprehensive error reporting</div>  
<div>\## How to Use</div>  
<div>1. **Open the Tool**: Open `index.html` in your web browser</div><div>2. **Upload GPX File**:</div><div>- Drag &amp; drop a GPX file onto the upload zone, or</div><div>- Click "Select File" to browse for a GPX file</div><div>3. **Configure Options**:</div><div>- Set a custom KML document name</div><div>- Choose track color and width</div><div>- Select which elements to include (waypoints, tracks, routes)</div><div>4. **Convert**: Click "Convert to KML"</div><div>5. **Download**: Click "Download KML File" to save the result</div>  
<div>\## Supported GPX Elements</div>  
<div>\### Waypoints (`&lt;wpt&gt;`)</div><div>- Converted to KML Placemarks</div><div>- Preserves name, description, and location</div><div>- Includes elevation data when available</div><div>- Uses standard pushpin icon styling</div>  
<div>\### Tracks (`&lt;trk&gt;`)</div><div>- Converted to KML LineString paths</div><div>- Supports multiple track segments</div><div>- Preserves track name and description</div><div>- Maintains elevation and time data</div><div>- Applies configurable styling</div>  
<div>\### Routes (`&lt;rte&gt;`)</div><div>- Converted to KML LineString paths</div><div>- Preserves route name and description</div><div>- Includes all route points with names</div><div>- Uses same styling as tracks</div>  
<div>\## KML Output Format</div>  
<div>The generated KML includes:</div>  
<div>```xml</div><div>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</div><div>&lt;kml xmlns="http://www.opengis.net/kml/2.2"&gt;</div><div>&lt;Document&gt;</div><div>&lt;name&gt;Your Custom Name&lt;/name&gt;</div><div>&lt;Style id="trackStyle"&gt;</div><div>&lt;!-- Track styling (color, width) --&gt;</div><div>&lt;/Style&gt;</div><div>&lt;Folder&gt;</div><div>&lt;name&gt;Waypoints&lt;/name&gt;</div><div>&lt;!-- Waypoint placemarks --&gt;</div><div>&lt;/Folder&gt;</div><div>&lt;Folder&gt;</div><div>&lt;name&gt;Tracks&lt;/name&gt;</div><div>&lt;!-- Track paths --&gt;</div><div>&lt;/Folder&gt;</div><div>&lt;Folder&gt;</div><div>&lt;name&gt;Routes&lt;/name&gt;</div><div>&lt;!-- Route paths --&gt;</div><div>&lt;/Folder&gt;</div><div>&lt;/Document&gt;</div><div>&lt;/kml&gt;</div><div>```</div>  
<div>\## Technical Details</div>  
<div>\### File Requirements</div><div>- **Supported formats**: `.gpx` and `.xml` files</div><div>- **Encoding**: UTF-8 (standard GPX format)</div><div>- **Schema**: Standard GPX 1.1 format</div>  
<div>\### Browser Support</div><div>- Modern web browsers with File API support</div><div>- JavaScript enabled</div><div>- No server-side processing required</div>  
<div>\### Processing Steps</div><div>1. **File Validation**: Checks file extension and format</div><div>2. **XML Parsing**: Uses DOM Parser to read GPX structure</div><div>3. **Data Extraction**: Parses waypoints, tracks, and routes</div><div>4. **KML Generation**: Creates properly formatted KML with styling</div><div>5. **Download**: Generates downloadable blob with correct MIME type</div>  
<div>\## Error Handling</div>  
<div>The tool provides detailed error messages for:</div><div>- Invalid file formats</div><div>- Corrupted XML/GPX files</div><div>- Missing coordinate data</div><div>- Parsing failures</div><div>- Browser compatibility issues</div>

<div>\## Contributing</div>  
<div>To add features or fix bugs:</div>  
<div>1. Test with various GPX files from different GPS devices</div><div>2. Ensure KML compatibility with Google Earth and mapping apps</div><div>3. Maintain responsive design for mobile devices</div><div>4. Follow existing code structure and commenting style</div>  
<div>\## Known Limitations</div>

<div>\## Examples</div>  
<div>\### Input GPX</div><div>```xml</div><div>&lt;gpx&gt;</div><div>&lt;wpt lat="40.7128" lon="-74.0060"&gt;</div><div>&lt;name&gt;New York City&lt;/name&gt;</div><div>&lt;/wpt&gt;</div><div>&lt;trk&gt;</div><div>&lt;name&gt;Central Park Walk&lt;/name&gt;</div><div>&lt;trkseg&gt;</div><div>&lt;trkpt lat="40.7829" lon="-73.9654"&gt;&lt;ele&gt;45&lt;/ele&gt;&lt;/trkpt&gt;</div><div>&lt;trkpt lat="40.7831" lon="-73.9656"&gt;&lt;ele&gt;47&lt;/ele&gt;&lt;/trkpt&gt;</div><div>&lt;/trkseg&gt;</div><div>&lt;/trk&gt;</div><div>&lt;/gpx&gt;</div><div>```</div>
