Geotagging Multiple .gpx Files to Photos with Exiftool - A Powerful Tool for GIS Enthusiasts

As a GIS enthusiast, you're likely aware of the importance of accurately geotagging your photos and videos. This process involves attaching geographic coordinates to images, allowing you to visualize their location on a map. In this article, we'll explore how to use Exiftool, a powerful command-line tool, to geotag multiple .gpx files to photos.

What is Exiftool?

Exiftool is a free and open-source software tool that allows you to read, write, and edit metadata in image files. Metadata is information embedded in an image file, such as camera settings, GPS coordinates, and timestamps. Exiftool can be used to extract, add, or modify this metadata, making it a valuable tool for geotagging images.

Why Use Exiftool?

Exiftool stands out from other geotagging tools due to its flexibility and customization options. It allows you to specify the coordinates, date, and time of each image, ensuring that your metadata is accurate and consistent. Additionally, Exiftool can handle multiple files at once, making it an efficient tool for batch processing.

Geotagging with Exiftool

To geotag multiple .gpx files to photos using Exiftool, follow these steps:

1. Download the Exiftool software from its official website and install it on your computer.

2. Open a command-line interface or terminal window.

3. Navigate to the directory containing your image files and the .gpx file you want to use for geotagging.

4. Use the following command to specify the .gpx file and the images you want to geotag: `exiftool -gps lat lon -d 'YYYY:MM:DD HH:MM:SS' *.jpg`

* Replace `lat` and `lon` with the coordinates from your .gpx file.

* Replace `YYYY:MM:DD HH:MM:SS` with the date and time format you want to use for your images.

* The `*.jpg` at the end specifies that you want to geotag all JPEG files in the directory.

Example:

```

exiftool -gps 52.520006 -122.030557 -d '2023:02:10 14:30:00' *.jpg

```

This command will geotag all JPEG files in the current directory using the coordinates from your .gpx file and the specified date and time format.

Tips and Tricks

* Make sure to specify the correct coordinates, date, and time formats for your images.

* You can use Exiftool's built-in support for multiple file extensions by replacing `*.jpg` with a comma-separated list of file extensions (e.g., `*.jpg, *.png, *.jpeg`).

* To geotag files in a specific directory or subdirectory, use the `-r` option followed by the path to that directory (e.g., `-r /path/to/directory`).
