Other Repositories

This repository (ie, otm-core) is but one of a few separate repositories that together compose the OpenTreeMap project. Others include:

Deprecated Repositories

OpenTreeMap has a long history. These repositories still exist, but are deprecated and no development is happening here moving forward.

  • OpenTreeMap - Otherwise known as "OTM1", this is previous generation codebase of OpenTreeMap. It has been entirely superceded by this repository and the others listed above. However, there are some live tree map sites still running on the old OTM1 code, and so we have left it up for archival purposes.
