Wikimedia Maps


August 2021 update: On third-party usage

This page is where developments relating to Wikimedia maps will be announced and discussed after July of 2018. It takes over from the Map improvements 2018 page, which documented a project that added various upgrades in the first half of that year, and from the Wikimedia Maps/2015-2017 page, which preceded that.


Maintain the Wikimedia maps infrastructure including the Kartographer and Kartotherian services.


Bug reports and requests can be made in Phabricator. See How to report a bug. Please tag tasks with #Maps.
