MapSCII is a Braille & ASCII world map renderer for your console, based on OpenStreetMap
npm install mapsciiA node.js based Vector Tile to Braille and ASCII renderer for xterm-compatible terminals.
``sh`
$ telnet mapscii.me
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 optimized algorithms for a smooth experience
* 100% pure JavaScript! :sunglasses:
With a modern node installation available, just start it with
``
npx mapscii
If you haven't already got Node.js >= version 6.14, 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`
In any of the supported Linux distros:
sudo snap install mapscii
(This snap is maintained by @nathanhaines)
This is pretty simple too.
``
mapscii
* Arrows up, down, left, right to scroll around
* Press a or z to zoom in and out
* Press c to switch to block character mode
* 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.
for converting RGB values to closest xterm-256 color code for mouse handling for input handling to determine visual string lengths#### Discovering the map data
* vector-tile for VectorTile parsing
* pbf for Protobuf decoding
* mbtiles for MBTiles parsing
#### Juggling the vectors and numbers
* earcut for polygon triangulation
* rbush for 2D spatial indexing of geo and label data
* bresenham for line point calculations
* simplify-js for polyline simplifications
#### Handling the flow
* bluebird for all the asynchronous Promise magic
* node-fetch for HTTP requests
* userhome` to determine where to persist downloaded tiles
* [ ] mouse control
* [ ] hover POIs/labels
* [ ] hover maybe even polygons/-lines?
* Styler
* [ ] respect zoom based style ranges
* Renderer
* [ ] download and process tiles in a different thread (#3)
* [ ] optimize renderer for large areas (#6)
* [ ] label drawing
* [ ] multi line label?
* TileSource
* [ ] implement single vector-tile handling
* lukasmartinelli & manuelroth for all their work on OSM2VectorTiles (global vector tiles from OSM Planet)
* mourner for all his work on mindblowing GIS algorithms (like the used earcut, rbush, simplify-js, ..)
