Convert GeoJSON to KML.

npm i geokml

yarn add geokml

pnpm i geokml

ESM

import { toKML } from 'geokml';

CommonJS

const { toKML } = require('geokml');

// kml is a string of KML data, geojsonObject is a JavaScript object of
// GeoJSON data
const kml = toKML(geojsonObject);

// grab name and description properties from each object and write them in
// KML
const kmlNameDescription = toKML(geojsonObject, {
  name: 'name',
  description: 'description',
});

// name and describe the KML document as a whole
const kmlDocumentName = toKML(geojsonObject, {
  documentName: 'My List Of Markers',
  documentDescription: 'One of the many places you are not I am',
});

Given GeoJSON data as an object, return KML data as a string of XML.

options is an optional object that takes the following options:

The property to name/description mapping: while GeoJSON supports freeform properties on each feature, KML has an expectation of name and description properties that are often styled and displayed automatically. These options let you define a mapping from the GeoJSON style to KML's.

• name: the name of the property in each GeoJSON Feature that contains the feature's name
• description: the name of the property in each GeoJSON Feature that contains the feature's description

Timestamp: KML can associate features with a moment in time via the TimeStamp tag. GeoJSON doesn't have a comparable field, but a custom property can be mapped

• timestamp: the name of the property in each GeoJSON Feature that contains a timestamp in XML Schema Time (yyyy-mm-ddThh:mm:sszzzzzz)

Document name and description: KML supports name and description properties for the full document.

• documentName: the name of the full document
• documentDescription: the description of the full document

simplestyle-spec support:

• simplestyle: set to true to convert simplestyle-spec styles into KML styles
• iconBaseUrl: Mapbox deprecated their icons API (pointing to "https://api.tiles.mapbox.com/v3/marker/") so you can customize it (e.g.: "https://my-icon-api.com/icons/"). This was the motive for this fork.
