Tools to convert ArcGIS JSON geometries to GeoJSON geometries and vice versa.


npm install arcgis-to-geojson-utils


var arcgisToGeoJSON = require('arcgis-to-geojson-utils').arcgisToGeoJSON;
var geojsonToArcGIS = require('arcgis-to-geojson-utils').geojsonToArcGIS;

// parse ArcGIS JSON, convert it to GeoJSON
var geojson = arcgisToGeoJSON({
    "spatialReference": {
      "wkid": 4326

// take GeoJSON and convert it to ArcGIS JSON
var arcgis = geojsonToArcGIS({
  "type": "Point",
  "coordinates": [45.5165, -122.6764]

// this way works too
var esriUtils = require('arcgis-to-geojson-utils');

esriUtils.geojsonToArcGIS(/* ... */);
esriUtils.arcgisToGeoJSON(/* ... */);

This package is distributed as a UMD() module and can also be used in AMD based systems or as a global under the ArcgisToGeojsonUtils namespace.
Thanks to @JeffJacobson, TypeScript typings and tests can be found on npm.
We recommend using --moduleResolution Node to ensure the compiler recognizes the types.
