geoJson > arcJson
I put together a dead simple interface to convert GeoJSON to ArcJSON using the Esri GeoJSON Utils repo. I also threw in a feature to preview the result on a map, but it’s a bit spotty…
brightrain.github.io/geoconverter
It really is just a light wrapper around GeoJSON Utils.
Include, create, use:
<script src=”https://gist.github.com/brightrain/6252925.js"></script>
I built this for a few reasons:
- I wanted to play with the excellent GeoJSON creation/editing tool from @tmcw: geojson.io
- And I wanted to experiment with the new Bootstrap 3 flat design, which was a major departure from earlier versions in both look and behavior.
The idea came when I needed a coarse polygon dataset representing world regions and wanted to publish it as a map service for use in an ArcGIS JavaScript API application.
It was super simple to create the handful of regions I needed with geojson.io, and I ended up with GeoJSON polygons in just a few minutes.
Then I needed to get them into an ArcGIS feature service.
Uh oh — although it’s looking increasingly imminent, GeoJSON is not supported in the ArcGIS world currently. So here we are.
The new developers.arcgis.com site allowed me to quickly create and publish a new feature service to hold the new data. I copied the output from geojson.io, pasted it into a text box, hit the button, and I had ArcJSON.
Another copy/paste into the addFeatures endpoint here and I had my regions published in my map service.
Important note
If you need the same workflow, you must unwrap the ArcJSON before posting to addFeatures. Meaning: remove the outer "features" object and send only the array.
You’re stripping this bit (and the final curly brace):
Definitely “innovation time” — this is just a bridge across open water until Esri provides full support for GeoJSON.
Let me know if you find it useful.
