img-to-map v0.1.0

Img to Map CLI Tool

img-to-map is a command line tool for generating GPX (GPS Exchange Format) files from images that contain GPS data. The tool uses ExifTool to extract the geographical coordinates from your photos and create a GPX track from them.

GPX is a widely accepted data format that allows for the sharing and visualizing of GPS data across a variety of platforms and services. Once you've generated a GPX file with img-to-map, you can upload it to platforms such as Strava or Google Maps, or use other tracking services or map software that supports the GPX format. This opens a plethora of possibilities, including analyzing your journey, sharing your travel routes with others, or re-living your adventures.

Installation

Before using img-to-map, you need to have ExifTool installed on your system.

Installation:

npm install -g img-to-map

Or by using npx:

npx img-to-map

Usage

img-to-map [options]

The tool is configurable with the following options:

Examples

Generate a GPX track with default settings:

To generate a GPX track file with the default settings, you only need to specify the folder with your photos:

img-to-map --folder /path/to/photos

The tool will generate a GPX file named track.gpx in the current directory. The track will have the name "My Track" and the type hiking.

Generate a GPX track with custom settings:

To customize the output, you can use any of the available options. For example, you can set a custom track name and output file:

img-to-map --name "My Vacation" --folder /path/to/photos --output "vacation.gpx"

This will generate a file named vacation.gpx with the track name "My Vacation".

Split tracks by days:

If you have photos from multiple days and you want to generate a separate track for each day, you can use the --split-by-days option:

img-to-map --folder /path/to/photos --split-by-days

The tool will generate a separate GPX file for each day.

Extend your GPX track with multiple additional data segments

Sometimes, your journey may be spread across several GPX files, be it from different devices or different parts of your adventure. The --extend option offers flexibility by allowing you to merge multiple GPX files into your primary track, ensuring that your final track is comprehensive.

For instance, if you have two additional GPX files named segment1.gpx and segment2.gpx that contain different parts of your journey, you can integrate both into your main track.

Use the command:

img-to-map --folder /path/to/photos --extend /path/to/segment1.gpx --extend /path/to/segment2.gpx

This command takes the primary track data from your photos and successively merges it with the tracks from segment1.gpx and segment2.gpx. The final output is a consolidated GPX file that seamlessly connects the segments from all sources, giving a holistic view of your entire adventure.

Remember, you can use the --extend flag multiple times in a single command to incorporate as many additional GPX files as needed.

Add viewpoints to your GPX track

To enhance your GPX track with specific viewpoints from a JSON file, use the --viewpoints option. This option allows you to provide additional context or highlight specific locations on your journey.

Given a viewpoints.json file structured as:

[
  {
    "lat": 48.0908777777778,
    "lon": 24.5844305555556,
    "elevation": 1897,
    "name": "Camp, day 1",
    "symbol": "Campground"
  },
  {
    "lat": 48.1230055555556,
    "lon": 24.5399694444444,
    "elevation": 1755.3,
    "name": "Camp, day 2",
    "symbol": "Campground"
  }
]

Use the command:

img-to-map --folder /path/to/photos --viewpoints /path/to/viewpoints.json

This will generate a GPX track that includes the specified viewpoints, marking "Camp, day 1" and "Camp, day 2" with the symbol for "Campground". These can be visualized as points of interest when you upload the GPX file to platforms that support such features.

If you encounter any problems or need to get more information about what the tool is doing, you can enable debugging output with the --debug option:

img-to-map --folder /path/to/photos --debug
