# V™
VTM (Vector Tile Map) was developed within the [OpenScienceMap](https://github.com/opensciencemap) project.
**This fork continues VTM development and provides compatibility with [Mapsforge](https://github.com/mapsforge/mapsforge).**
See the **[integration guide](docs/Integration.md)** and [changelog](docs/Changelog.md). And read through [how to contribute](docs/CONTRIBUTING.md) guidelines.
If you have any questions or problems, don't hesitate to ask the Discussions for help.
## Features
- Java map library
- OpenGL vector-tile rendering
- Themeable vector layers ([render themes](docs/Rendertheme.md))
- Support for multiple tile sources:
- OpenScienceMap vector tiles
- Mapsforge vector maps
- MBTiles vector & raster maps
- Mapbox vector tiles (e.g. Mapilion, Mapzen, Nextzen, OpenMapTiles)
- GeoJSON vector tiles (e.g. Mapzen, Nextzen)
- Raster tiles: any quadtree-scheme tiles as texture
- Backends:
