Grunt task for converting KML and GPX files to GeoJSON and TopoJSON

Build Status Code Climate Dependency Status Built with Grunt Analytics

Getting Started

This plugin uses Grunt, toGeoJSON, TopoJSON, Geobuf, and jsdom.

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-togeojson --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


The "togeojson" task


In your project's Gruntfile, add a section named togeojson to the data object passed into grunt.initConfig().

Configure the files list as described in the multi task section of the Grunt documentation.

  togeojson: {
    maps: {
      files: {
        // Target-specific file lists and/or options go here.


Conversion will use the same basename of the source file for the destination file.
