## Overview
GeoGPXer provides an easy-to-use API to parse GPX files and convert them into a GeoJSON FeatureCollection, making it suitable for use in web mapping applications and geographic data visualization.
## Features
- **Convert GPX to GeoJSON**: Supports waypoints, tracks, and routes.
- **Handle Extensions**: Converts GPX `` to prefixed GeoJSON properties to avoid conflicts.
- **No External Dependencies**: Lightweight and easy to integrate into various projects.
## Usage
To use GeoGPXer, create an instance of `GeoGPXer` and use its methods to perform the conversion from GPX strings to GeoJSON objects.
### Example
```javascript
var geoGPXer = new GeoGPXer(); // Create a new instance of GeoGPXer
// Sample GPX data input
const gpxData = `...your GPX data...`;
// Parse the GPX data
const xmlDoc = geoGPXer.read(gpxData);
// Convert to GeoJSON
const geoJson = geoGPXer.toGeoJSON(xmlDoc);
console.log(geoJson);
```
## Key Methods
- read(gpxText): Parses a GPX string into an XML Document using DOMParser.
- toGeoJSON(document): Converts an XML Document into a GeoJSON FeatureCollection.
- extractProperties(node): Extracts properties from a GPX node, including handling of by prefixing property names.
