## VTM - Very experimental Tile Map library
|
|
|
|
Future development branch based on https://github.com/opensciencemap/vtm-android
|
|
|
|
VectorTileMap is part of the OpenScienceMap project, developed at University of Bremen.
|
|
http://www.opensciencemap.org
|
|
|
|
### Features
|
|
- Java map library
|
|
- OpenGL vector-tile rendering
|
|
- Themeable vector layers
|
|
- Support for multiple tile sources: primary opensciencemap (.vtm)
|
|
- vector: partially mapbox vector-tile and mapsforge files
|
|
- bitmap: any quadtree-scheme tiles as texture
|
|
- Backends for Android, Desktop and HTML5/WebGL (through libgdx and GWT)
|
|
|
|
### Notes
|
|
- checkout required libraries with 'git submodule init && git submodule update'
|
|
- To set up your own tile server for .vtm tiles see https://github.com/opensciencemap/TileStache/tree/master/TileStache/OSciMap4
|
|
- Almost everything is still in early/experimental stage and subject for being rewritten
|
|
- Projects are expected to be build within eclipse (for now)
|
|
- pull requests welcome :)
