V™

VTM (Vector Tile Map) was developed within the OpenScienceMap project.

This fork is in sync with VTM development and provides compatibility with latest Mapsforge. Use this branch at your own risk, as it contains untested features or is inconsistent in the git history.

See the integration guide and changelog. And read through how to contribute guidelines.

If you have any questions or problems, don't hesitate to ask our public forum for help.
