A node.js based Vector Tile to Braille and ASCII renderer for xterm-compatible terminals.

• Use your mouse to drag and zoom in and out
• Discover Point-of-Interests around any given location
• Highly customizable layer styling with Mapbox Styles support
• Connect to any public or private vector tile server
• Or just use the supplied and optimized OpenStreetMap based one
• Work offline and discover local VectorTile/MBTiles
• Compatible with most Linux and OSX terminals
• Highly optimizied algorithms for a smooth experience
• 100% pure Coffee-/JavaScript! 😎

If you haven't already got Node.js >= version 4, then go get it.

npm install -g mapscii

If you're on OSX, or get an error about file permissions, you may need to do sudo npm install -g mapscii

This is pretty simple too.

mapscii

• Arrows up, down, left, right to scroll around
