If you're on Windows, use the open source telnet client PuTTY to connect.
- 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 OSM2VectorTiles based one
- Work offline and discover local VectorTile/MBTiles
- Compatible with most Linux and OSX terminals
- Highly optimizied algorithms for a smooth experience
How to install it locally
If you haven't already got Node.js >= version 4.5, 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.
- Arrows up, down, left, right to scroll around
- Press a or z to zoom in and out
- Press q to quit
If your terminal supports mouse events you can drag the map and use your scroll wheel to zoom in and out.
