Official Source Code Archive

In accordance with the USGS public access plan, while source code developed by the USGS may also be found on third-party distribution repositories, the authoritative version of all such software is maintained by the USGS in this publicly accessible archive.

All USGS employees and contractors automatically have accounts and may log in using the "USGS Login" button on this page. External collaborators may log in by entering their provided username and password on this page and clicking the "Sign in" button. A USGS employee must submit a form to request an external collaborator account on their collaborator's behalf. For additional details on this process, the USGS employee may contact GS Help Git by email.
