This is where the source code for  OpenStreetMap is managed.

Logging in

You can view anything here, but you'll need to log in to change anything.

Log in with your OpenStreetMap.org (main website) username or e-mail address and password. Note that your contributions will be identified by either your email address or username, depending on which you use. It would be ideal to choose which you prefer before contributing.

Reporting a bug

  1. View the list of tickets to make sure that your bug hasn't already been reported. You should also try searching.
  2. If it hasn't:
    1. Add a new ticket. You will need to log in first if you haven't already
    2. Enter your bug descriptively. Be sure you set the 'component' field (e.g. "website" or "potlatch (Flash editor)") so that it goes to the right person

You can also use this to request enhancements.

(If it is a bug in JOSM then report it in the  JOSM trac, not here.)

How to be a helpful bug reporter

Where you can, always provide "steps to reproduce" - in other words, a series of instructions that the developers can follow to reproduce your bug. The more you can do to pinpoint the problem, the more likely it'll be fixed.

  1. Give any pertinent details of your system (operating system and version, browser and version, etc.).
  2. If the problem is with a web page or web application, give its URL. If the problem is encountered with a particular set of data, say what (e.g. a location in OpenStreetMap).
  3. Explain what you are doing, click-by-click.
  4. Explain what you expect to happen.
  5. Explain what is happening instead.
