## 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 - 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 - pull requests welcome :) ### Demo work in progress.. http://city.informatik.uni-bremen.de/~jeff/map/#scale=17,rot=61,tilt=51,lat=53.075,lon=8.807 - hold middle mouse button to change view direction - Keys - g - toggle tile-grid layer - d - default theme - t - tubes theme ### Credits This library contains code from several projects: - mapsforge: based on 0.2.4 - osmdroid: some overlay code - libgdx: AsyncTask, some modfied classes - android: some Matrix code - Triangle: stripped down for simple triangulation (through jni)
