Some news about uMap!

Posted by ybon on 25 August 2023 in English. Last updated on 28 August 2023.

Since a few month, uMap has been integrated in a French state incubator, so things are moving quite a lot!

uMap is now ten years old, and is deployed on many instances around the world. The one I know well is hosted by OSM France, and is close to reach one million maps created and 100.000 users.

This incubation program is ported by the French “Accélérateur d’initiatives citoyennes”, it includes coaches and a small budget for non tech needs (UI/UX…). One goal of this program is to find financial support for uMap development and maintainance. A French administration, the Agence pour la cohésion des territoires, is the first uMap financial backer since a few months. This allowed us to put up a small team to work, part time, in uMap:

That’s great news! Until then, uMap was 100% developed on my spare time.

uMap is used a lot by French public agents, and this explains the support from the French state, to make this tool better, and more official. For this, a first step is an “official” instance for public workers:

We’ll be at the NEC - Numérique En Communs event (Bordeaux, France), on October 19th and 20th. See you there for more news and announcements!

What’s new in uMap, then ?

First, a huge cleaning, upgrade and bug fight in uMap code. Since a few years, my time available for uMap has been very low (I’ve been a baker for two years…), so the code urgently needed more love.

What else? Here are a few of the notable changes made recently in uMap, let’s go!

Docker image


Custom overlay

After years of people losing their secret edit link, now there will be no more excuse…

Chose some properties, uMap will compute all the values and let people filter data.

Starred maps

A cool way to keep tracks of maps made by others!

My Dashboard page

Very basic version of a dashboard page, where to retrieve all our maps, with more metadata and actions than the previous flat maps list.

Better control of default map view

Allow to edit basic user profile information

Useful for changing the username and adding more than one OAuth provider.


  • allow to control icon opacity
  • allow to sort reverse (by adding a - before the property)
  • allow to control links target: same window, new tab, parent window
  • add Ctrl-Shift-click shortcut to edit features’s datalayer when clicking on the feature shape
  • better natural sort of features
  • allow non ascii chars in variables
  • Make fromZoom and toZoom options available for all layers
  • When map has max bounds set, use those bounds for limiting search

Full changelog.

What’s next ?

A user research session has started by Raywan (who helped us on the bizdev part) and Aurélie, targeted mainly on public workers, but not exclusively.

Some topics on the pipe, from this research and from long waited features:

  • concurrent live editing of a map
  • define permissions at the datalayer level
  • better icon management
  • print a map
  • UX revamp
  • better user documentation
  • teams?
  • attachements support?

uMap issue management is on Github: Public roadmap is here:

If you want to give your opinion on what should be done first, please add emojis in the issues list. And if something is missing from the list, please create new ones to share your ideas!

How to contribute ?

It’s now finally possible to support uMap by donating on Liberapay or Open Collective. All amounts are welcome!

Help translating uMap in your language. uMap is available in 58 languages but many still lack between 15 to 20% to be complete.

And of course, contribute to the code!

Cheers, and thanks for your warm support since ten years!

That’s indeed a huge step, getting recognized and backed up by the state. Congratulations and thank you for your work on making uMap

Super news ! A UI/UX design, a skill unfortunately too rarely deployed within OSM projects, I’m very happy to see it happen !

Mes félicitations les plus sincères. C’est une très belle nouvelle. Continuez comme ça !

Excellent work. I’m a fairly new user and am amazed by how polished Umap is.
