Panoramax is a federation offering geolocated street-level pictures. Pictures are offered through a decentralized architecture, with a set of free and open-source tools. In other words, it is "like a self-hosted Street View"[2] that does not impose its own app and gives you the right to fork the server.

The main selling points are:

  • self-hostable, as a public instance or in your private organization
  • free-licensed server (unlike Mapillary or Mapilio)
  • freedom to choose or develop your favorite client app
  • federation through a meta-catalog, which gives a single entrypoint (API, web viewer) to all publicly available servers

Instances

Some services store in-app uploads on custom Panoramax servers, which means that photos are accessible not only through an in-browser slippy map (i.e. the default Panoramax frontend), but also via the federation API, the Panoramax API, and the STAC API.

URL Region Publicly viewable Publicly editable License Other notes
https://panoramax.xyz 🌐 Global Yes No Mixed The meta-catalog list all pictures available across the public federation. After uploading an image, you may have to wait some time before it is visible on the meta-catalog[3].
https://panoramax.openstreetmap.fr 🇫🇷 France (and outside for tests) Yes Yes, with OSM-account CC-BY-SA 4.0 (see below) by OSM France

In the short term, OSM FR can host pictures from the outside of France, but worldwide coverage is not sustainable in the long term, due to storage limits (and costs). Therefore, it is preferred that other local communities set up their own federated instances.[4]

https://panoramax.mapcomplete.org 🌐 Global Yes Yes, but only via https://mapcomplete.org, requires OSM-account CC-BY-SA 4.0 Images uploaded in MapComplete are stored here

OSM-France adopted CC-BY-SA for the pictures, but also grant a right to create non photographic derivates under CC-BY or ODbL.

Software

As Panoramax is a federation, the main matter is to agree on standards. Servers have to offer their pictures through a STAC API. Beyond that, any compliant server can be a part of Panoramax.

Main software used for Panoramax is listed below.

Server-side

All servers are running under the Panoramax API, which is fully free and open-source. It's a Python and Flask API, relying on a PostgreSQL database with PostGIS. It handles users, as well as uploading and serving of pictures.

Client-side

Many clients can be made available for Panoramax, as long as they accept STAC and/or WFS servers.

As of now, the following clients are available:

  • Panoramax website, the front-end of public servers
  • Panoramax web viewer, a stand-alone JS viewer
  • Panoramax CLI interface, a Python-based CLI tool for uploading and downloading images
  • STAC-compatible clients
  • Panoramax-js, a Typescript library with which one can upload images to a Panoramax instance and with some other API calls made available; developed and used by MapComplete
  • MapComplete, an OSM editor and viewer, lets users browse nearby pictures from Panoramax and also upload pictures to Mapcomplete's own Panoramax instance. They moved all old images (hosted on imgur) to their panoramax-instance. This is documented in this issue
  • iD support with ability to filter by capture date, contributor and image type has been implemented, see screenshot below

  • OsmApp.org shows Panoramax-images as well but doesn't (yet) shows a correct attribution (as of 2024-11-21)

Work in progress:

Third-party viewers

  • In MapComplete, click a map feature, then click "Browse nearby pictures" in the panel at the right. This includes the pictures from the Panoramax meta-catalog - so not only the pictures that were uploaded to MapComplete.

For developers

To convert a panoramax-hash into the src for an image, query https://api.panoramax.xyz/api/search/?ids=<hash> which will give you a .json. A normal-sized image is available at features[0].assets.sd. Use .hd or .thumb for other sizes

Alternatively, one can use https://api.panoramax.xyz/api/pictures/{hash}/sd.jpg
