This page describes a historic artifact in the history of OpenStreetMap. It does not reflect the current situation, but instead documents the historical concepts, issues, or ideas.
Potlatch 2 (sometimes referred to as P2) was an OpenStreetMap editor. It required an Adobe Flash plugin in the browser; therefore it did not support all browsers (no plugin was available for some).
Impact on OpenStreetMap
Potlatch 2 was completely rewritten from the original Potlatch 1. Both once were the standard editors of OpenStreetMap data. iD took over Potlatch 2's role in 2013.
Reason for being historic
Potlatch 2 depends on Adobe Flash to run in a browser. Major browsers removed their support of Flash and blocked the scripts on 12 January 2021 and Potlatch 2 was removed from OSM website. Potlatch 2 was converted into a desktop application (Potlatch 3) running on Windows and MacOS with the support of OSMF.

How to use Potlatch 2

Basic editing

Advanced editing


P2's distinguishing characteristic is that it's extraordinarily ergonomic for moderately familiar users, without ever having too complex an interface. With a handful of keyboard shortcuts you can zip about the map and perform common editing actions efficiently: for example, you can skip 10 nodes back/forward along a way with one keypress, jump to the other end of the way with another, then assign a set of multiple tags to the way (which you've previously recorded) with another single keypress[1].


As of December 2020, Potlatch 2 is no longer maintained. See Developer documentation for some historic development and feedback information.
