Converts ESRI json to geojson

esri2geo

This is a tool to turn esri json to geojson, which should work in the browser, in a worker, and in node.

Looking for the esri toolbox? It's over at it's own repo to hopefully merge with @feomike's version

Sync Method

var geoJSON = toGeoJSON(esriJSON);

// do something with geoJSON object

Async Methods

// callback for resulting data
function handleGeoJSON(err, data) { 
  if (err) {
    console.error(err);
    return;
  }
  
  // data => GeoJSON
  // do something with it..
}

toGeoJSON(esriJSON, handleGeoJSON);
// or
toGeoJSON('same/origin/url/to/esriJSON', handleGeoJSON);

Using From Node

You can install from npm:

npm install esri2geo --save

The use from your node app like so:

var esri2geo = require('esri2geo');

esri2geo(esriJSON, function (err, data) {
  // handle error, deal with data here
});

Using with Webpack 2.x

Install from npm as you would with node.

To avoid Webpack warnings about missing node modules, add this to your webpack config:

node: {
    console: true,
    fs: 'empty',
    net: 'empty',
    tls: 'empty',
    dns: 'empty',
    dgram: 'empty'
},

Using as standalone browser component

Download the esri2geo.js file, include on your page and reference it through the esri2geo namespace:

esri2geo.toGeoJSON(esriJSON, function (err, data) {
  // handle error, deal with data here
});

Note: You can also use the other methods above.

Disclaimer: not endorsed by, or have anything to do with ESRI.

esri2geo's Issues

check geo once

I can probobly get by with checking what the geometry is once at the being and avoiding the parseGeo function

Feature class with no features

will give an error and stop if there are not features in the feature class.

calling toGeoJSON throw a 'toGeoJSON is not defined' error

Hi, since ec9da97 calling toGeoJSON doesn't work anymore (toGeoJSON is not defined), i have to call esri2geo.toGeoJSON. Maybe the readme needs an update ?

calling toGeoJSON without callback throw an error

Calling toGeoJSON witout callback argument throw this error :

TypeError: cb is not a function
esri2geo.js
Line 40

merge feature classes

if you have a couple features that esri dosn't like together (point and line) be able to merge them into one GeoJSON, will have to do something about oids

csv

write to csv, but first figure out what kind of geometry I should for csv.

invalid geos

I bet you ESRI can also have polygons with 2 points (len = 3) and lines with 1 point (len=2)

write toolbox feature by features

currently we have to get the whole thing in memory first.
