A TileStrata plugin for rendering mapnik vector tiles (pbf) into raster images. Use the tilestrata-vtile plugin for generating the vector tiles. To use this plugin, you must have node-mapnik in your dependency tree.

Sample Usage

var vtile = require('tilestrata-vtile');
var vtileraster = require('tilestrata-vtile-raster');
var opts_vector = {
    xml: '/path/to/map.xml',
    tileSize: 256,
    metatile: 1,
    bufferSize: 128
var opts_raster = {
    xml: '/path/to/map-vt.xml',
    tileSize: 256,
    metatile: 1,
    bufferSize: 128
server.layer('myvectortiles', {maxZoom: 14})
    .route('t.png').use(vtileraster(opts_raster, {
        tilesource: ['myvectortiles', 't.pbf']
    .route('i.json').use(vtileraster(opts_raster, {
        tilesource: ['myvectortiles', 't.pbf'],
        interactivity: true


If the maxZoomproperty is set on the vector tile layer, the plugin will render higher zoom level tiles with the vector tiles from the max zoom level.

Mapnik XML Notes

tilestrata-vtile expects a typical mapnik xml file - the same as tilestrata-mapnik would expect. The XML for tilestrata-vtile-raster must have specialized for using vector-tiles however. It needs to differ from the typical xml file in the following ways:

  • The srs property must be removed or set to Web Mercator for each layer. Mapnik reprojects the source data before putting it into vector tiles
  • The Datasource for each layer must be removed. Mapnik will try to get the data from the datasource instead of the vector tile if Datasource is still set
