HERE JSON to GeoJSON

JavaScript library to transform HERE JSON objects to GeoJSON.

At the moment only a subset of the JSON response types provided by the HERE REST APIs is supported. This will be extended from time to time.

Disclaimer

This is not an official HERE product!

Be sure to respect the HERE Service Terms when using their API.

Usage

To use this library in an HTML-web-application just include the JavaScript-file at dist/hj2gj.js into your HTML-page. Otherwise just import this library as module like in the snippet below:

import {readIsolines} from 'here-json2geojson';

var hereIsolineResponse = // The response of the HERE REST API call
var isolineFeatColl = readIsolines(hereIsolineResponse);

Build the library on your own

> npm install
> npm run dist

Afterwards the single-file-build of the library is available under dist/hj2gj.js
