TrailView - Garmin KML Viewer

TrailView is a simple PHP application that fetches and displays data from a Garmin MapShare KML file. The app extracts GPS coordinates, velocity, and other data from the KML feed and provides a link to open the location in Google Maps. It's designed for users who want to visualize their trail or outdoor activity data in an easy-to-read format.

Features

• Fetch KML Data: Provides Garmin MapShare details like coordinates, speed (in mph), and the last updated timestamp.
• Google Maps Integration: Generates a link to open the last recorded GPS location in Google Maps.
• Garmin MapShare Link: Provides a direct link to the MapShare page.
• Clipboard Functionality: Users can copy the GPS coordinates to their clipboard.
• Automatic Page Refresh: A button to refresh the displayed data.

How It Works

1. Input: The app accepts either a Garmin MapShare URL or a user-specific identifier (q parameter) via the query string.
   • Example: https://your-domain.com?q=DJFOX or https://your-domain.com?q=https://inreach.garmin.com/feed/share/DJFOX.
2. Processing: It fetches and parses the KML feed data associated with the provided Garmin MapShare link.
3. Output: Displays the extracted information including the placemark's name, last update timestamp, and speed. You can also view the location on Google Maps or the Garmin MapShare page.

Example Usage

Default Example

If no input (q parameter) is provided, the app defaults to an example Garmin MapShare ID:

• KML Feed: https://inreach.garmin.com/feed/share/DJFOX
• MapShare Link: https://share.garmin.com/DJFOX

User Input

You can also pass your own Garmin MapShare ID or feed URL:

https://your-domain.com/?q=<Garmin-MapShare-ID-or-URL>

Example Query

https://your-domain.com/?q=DJFOX

or

https://your-domain.com/?q=https://inreach.garmin.com/feed/share/DJFOX

Running the PHP Native Web Server

You can quickly run the app using PHP's built-in web server, which is ideal for local development.

1. Open a terminal or command prompt.
2. Navigate to the directory where your PHP file is located.
3. Run the following command to start the PHP web server on port 8000:

php -S localhost:8000

4. Open a web browser and visit:

http://localhost:8000

You can now access your TrailView app locally.

Installation

1. PHP Environment: Ensure your web server is running PHP.
2. File Setup: Place the PHP file on your web server.
3. Access: Use a web browser to navigate to the PHP file and pass the Garmin MapShare URL or ID via the query string.
