GeoVisio is a complete solution for storing and serving your own 📍📷 geolocated pictures (like StreetView / Mapillary).
➡️ Give it a try at panoramax.ign.fr or geovisio.fr !
📦 Components
GeoVisio is modular and made of several components, each of them standardized and ♻️ replaceable.
All of them are 📖 open-source and available online:
| 🌐 Server | 💻 Client |
|---|---|
| API | Website |
| Blur API | Web viewer |
| GeoPic Tag Reader | Command line |
📷 GeoPic Tag Reader
This repository only contains the Python library to read and write standardized metadata from geolocated pictures EXIF metadata.
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()
