I have a GeoJSON dataset of the following format (LineString features):

  "type": "FeatureCollection",
  "crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },

  "features": [
    { "type": "Feature", "properties": { "id": 433775, "clazz": 72, "flags": 7, "source": 26697, "target": 48416, "kmh": 10, "time": 1 }, "geometry": { "type": "LineString", "coordinates": [ [ 13.3782144, 52.516451399999973, 0.0 ], [ 13.3782407, 52.5163161, 0.0 ] ] } },
    { /* [... around 13k features ...] */ },
    { "type": "Feature", "properties": { "id": 377768, "clazz": 51, "flags": 7, "source": 270569, "target": 270570, "kmh": 5, "time": 600 }, "geometry": { "type": "LineString", "coordinates": [ [ 13.388153799999985, 52.492538299999971, 0.0 ], [ 13.3881033, 52.4924441, 0.0 ] ] } }

For a research project I need this featureset to be cut into tiles of different zoom levels.

  • without generalization / simplification of geometries
  • without caching and writing results to new GeoJSON files on disk

I had a look at geojson-vt by mapbox and it seams it only generates the tiles on the fly, but I need them on the disk for further processing and investigation.

Is that possible? If so, how?


  • I'm on ArchLinux, command line tools like ogr2ogr or any C/C++ tools would be the best, regarding speed.
  • I already tried tilestache but it is totally broken and not well maintainted. Couldn't get it running.
  • Input aswell as output should be GeoJSON (or any vector format).
  • I'm talking about tiles a la Google Maps. The zoom factor for the resulting tiles should be 12, 13 or 14.

The result should be something like this:


A collection of GeoJSON tiles cut from the original vector data.

  • You say that you want to cut tiles without caching the results and then later you say that you want to have them on disk for further processing and investigation, I don't think that will be possible, Anyway take a look at tilestache.org it should have what you need – Hasan Mustafa Feb 10 '16 at 13:06
  • By modifying the mapbox code to save locally, perhaps with nodejs? But you don't really say what your environment is. – John Powell Feb 10 '16 at 13:07
  • Do you mean tile as a picture ? (e.g PNG) To summarize, you have one geojson file and you want many PNG tiles ? The answer from @HasanMustafa is right, your question is not clear. – Gustry Feb 10 '16 at 13:13
  • can you explain more about the different scales? this is vector data it doesn't really have a scale (especially if you don't simplify) – Ian Turton Feb 10 '16 at 13:16
  • I'm sorry, my head is so deep in that, I thought my question was clear. I added 4 updates. – Afri Feb 10 '16 at 13:20

I've written my own geojson map tiler driver in ruby. it's a quick and dirty ruby script to create geojson tiles from a postgis database using gdal/ogr. I could not find out how to cut the geojson directly, so I imported the json into a postgis database and exported them using ogr.

ogr is supposed to read geojson but I could not get the driver to work directly. maybe someone else can figure out how. here is how it worked for me using postgis:


  • ruby > 1.9.3, but ruby > 2.0.0 recommended
  • gdal/ogr > 2.0.0, the script utilizes the system command ogr2ogr
  • postgresql > 9.0.0, with postgis > 2.0.0 extension installed


setup environment

#!/usr/bin/env ruby

require 'mkmf'
require 'fileutils'
require './tiler/geojson.rb'

geojson_tiler = Tiler::GeoJson.new

set up working directory

geojson_tiler.set_basedir "/path/to/my/tiles"

enable verbose verbose output if desired

geojson_tiler.debug true

setup postgis database connection and sql query to retrieve geodataset

connection = "'PG:host=localhost dbname=distance user=qwertyu password=asdfghj'"
sql_query = "'SELECT id,flags,kmh,geom_way_web_mercator,time FROM streets WHERE time <= 600 ORDER BY time ASC'"
geojson_tiler.setup_db connection, sql_query

write full tile stack for zoom levels 0, 1, 2 and 3

(0..3).each do |zoom|
  geojson_tiler.write_tiles zoom

or write partial tile stack for zoom level 8 in range x: 136..138 and y: 82..84

geojson_tiler.write_tiles 8, 136, 138, 82, 84

syntax is zoom, xmin, xmax, ymin, ymax


is a full or partial stack of geojson tiles:


A little late to the game but if you want vector tiles in mbtiles format then I suggest the following:

(1) tippecanoe: Go to https://github.com/mapbox/tippecanoe and install it, if you are on a mac then brew install tippecanoe; Next you can tile the geojson directly using the following command: tippecanoe -e tiles -l layer_name file.geojson

Next, because they are gzipped using this method, you need to use the following commands(same if you use mbutil to unpack a .mbtiles file and get them that way):

cd /{the tiles folder}
gzip -d -r -S .pbf *;
find . -type f -exec mv '{}' '{}'.pbf \;

Then, in your style.json sources use the tile package in the following way(if you are serving them on a server then use http, if on a device use file:///, etc):

  "sources": {
        "customtiles": {
            "type": "vector",
            "tiles": [
            "minzoom": 0,
            "maxzoom": 18

And in your layers section: layers:[{ "id": "rds", "type": "line", "source": "customtiles", "source-layer": "layer_name", "paint": { "line-opacity": 0.8, "line-width": 2, "line-color": "#FF0000" } },...]

(2) Use the nodejs geojson-vt and vt-pbf method. I am personally using this as I am running it on Heroku and do not want to make a module using C++ or make a Heroku add on/use a child process. One great example for this is found at https://github.com/NYCPlanning/geojson2mvt. Essentially you can just change this script to output pbfs instead of mvts and it works.

One big difference is that geojson-vt simplifies a lot and tippecanoe does not. Thus geojson-vt tiles are much smaller and I have not found the quality degrade too much. For an on-the fly version check out this example: http://fuzzytolerance.info/blog/2016/07/31/Adding-GeoJSON-and-MVT-to-PostGIS-HTTP-API/
