geo2mvt

A Go program that converts a GeoJSON object into a Mapbox vector tile (mvt) object.

This tool is powered by orb.

Prerequisites

You need the following software installed,

• Go v1.13 or later

Building the tool

1. Run go build.

   go build
   

2. You will find geo2mvt in this directory.

Running the tool

geo2mvt -x X -y Y -z ZOOM INPUT OUTPUT

Parameters

• X: x coordinate of a tile to be generated.
• Y: y coordinate of a tile to be generated.
• ZOOM: zoom of a tile to be generated.
• INPUT: path to an input JSON file.
• OUTPUT: path to an output map vector tile file, which is a zipped PBF file.

As a Mapbox's map vector tile can contain multiple layers in a single tile, an input JSON file, multilayer GeoJSON file, can contain multiple GeoJSON objects inside. It associates a layer name with a corresponding GeoJSON object. A multilayer GeoJSON file looks like the following,

{
    "layers-1": {
        // GeoJSON object
    },
    "layers-2": {
        // GeoJSON object
    }, ...
}
