Collaborative custom mapping with OpenStreetMap data

uMap is an online open source application to make custom maps. It aims to make creating maps easy for anyone in a few clicks. It’s simple for basic use cases, whether you want to prepare a bike travel with your friends or communicate the current roadworks for your city. But it’s also flexible and extendable for more complex or custom ones: drawing or importing data, customizing style and interface, sharing access to a map… uMap is also easy to install and to maintain to enforce a decentralized model. It is already deployed in several European countries, and is translated in dozen of languages. Plus, it also allows to create maps anonymously. In this project, we will adding real-time collaboration on maps with local-first support - which will for instance help a lot with live events and mapping sprints - and clean up the user interface.
