Panoramax

Panoramax is a digital resource for sharing and using 📍📷 field photos. Anyone can take photographs of places visible from the public streets and contribute them to the Panoramax database. This data is then freely accessible and reusable by all. More information available at gitlab.com/panoramax and panoramax.fr.

📷 GeoPic Tag Reader

This repository only contains the Python library to read and write standardized metadata from geolocated pictures EXIF metadata. It can be used completely apart from all GeoVisio/Panoramax components for your own projects and needs.

Features

This tool allows you to:

• 🔍 Analyse various EXIF variables to extract standardized metadata for geolocated pictures applications (coordinates, date, orientation, altitude...)
• ✏️ Edit a picture to change its EXIF variables through a simpler command
• 💻 Either as Python code or as a command-line utility

Install

The library can be installed easily, for a quick glance:

pip install geopic_tag_reader
geopic-tag-reader --help

To know more about install and other options, see install documentation.

If at some point you're lost or need help, you can contact us through issues or by email.

Usage

This library can be used both from command-line or as Python module.

As command-line

To see all available commands:

geopic-tag-reader --help

To read metadata from a single picture:

geopic-tag-reader read --image /path/to/my_image.jpg

To edit metadata of a single picture, for example change its capture date:

geopic-tag-reader write \
	--input /path/to/original_image.jpg \
	--capture-time "2023-01-01T12:56:38Z" \
	--output /path/to/edited_image.jpg

Full documentation is also available here.

As Python library

In your own script, for reading and writing a picture metadata, you can use:

from geopic_tag_reader import reader, writer, model

# Open image as binary file
img = open("my_picture.jpg", "rb")
imgBytes = img.read()
img.close()

# Read EXIF metadata
metadata = reader.readPictureMetadata(imgBytes)
print(metadata)

# Edit picture EXIF metadata
editedMetadata = writer.PictureMetadata(
	picture_type = model.PictureType.equirectangular,
	direction = writer.Direction(125)
)
editedImgBytes = writer.writePictureMetadata(imgBytes, editedMetadata)

# Save edited file
editedImg = open("my_new_picture.jpg", "wb")
editedImg.write(editedImgBytes)
editedImg.close()
