Cuts a file pyramid of static vector tiles (.mvt) from a geojson file


We are using mapboxGL in The Capital Planning Platform, and needed an alternative to downloading large static data files for local rendering on the map. We didn't want to put them into a service that would require $ and maintenance, so static vector tiles seemed like a useful alternative for data that will not change very often.

How to Use

Install npm install geojson2mvt

geojson2mvt takes a geojson object and a config object, and builds the the pyramid in the specified output directory

var fs = require('fs');
var geojson2mvt = require('geojson2mvt');

const filePath = './bus_routes.geojson';

var options = {
  rootDir: 'tiles',
  bbox : [40.426042,-74.599228,40.884448,-73.409958], //[south,west,north,east]
  zoom : {
    min : 8,
    max : 18,
  layerName: 'layer0',

var geoJson = JSON.parse(fs.readFileSync(filePath, "utf8"));

// build the static tile pyramid
geojson2mvt(geoJson, options);

Check out /example for a test project that you can try locally


rootDir - string (required) - the filepath of the directory that will be the root of the file pyramid. It will be created if it doesn't exist.

bbox - array (required) - array of lat/lon bounds like [s,w,n,e]

zoom - object (required) - object with min and max properties for the desired zoom levels in the tile pyramid

layername - string (required) - the name of the layer in the vector tile that the data will be stored in. When displaying data from an MVT, you must specify which layer to use.
