Ditto: http://geojson.io/, https://github.com/mapbox/geojson.io.

There's a few npm modules for the command line, so you can do the likes of `geojsonio < some.geojson` or `togeojson my.{kml,gpx,…} | geojsonio`

geojson.io uses gist.github.com as a data store: http://geojson.io/#id=gist:anonymous/92dd314a02c072d658f4&ma...

I know of that website, it is made by a fellow OSMer, and while it's perfect for creating and editing GeoJSON, it lacks in simplicity of sharing maps (well, it depends on an external site for that). For example, MapBBCode Share maps can be embedded into posts on any forum or blog with MapBBCode plugin installed. Both sites were made with the same technology stack, though, namely Leaflet + Leaflet.draw.

And of course MapBBCode Share maps can be loaded in geojson.io: for example, http://geojson.io/#data=data:text/x-url,http%3A%2F%2Fshare.m... (replace zdjzk with map id).

Looks like this is a geojson.io fork.

Recently used GeoJSON to do a dirty GeoJSON to SVG conversion using Chrome Developer tools (don't ask...)

Love that it uses OpenID for the login!

If you are/were using MyOpenID, you can switch your delegation to IndieAuth since they are shutting down. It's an easy switch: http://aaronparecki.com/articles/2013/09/15/1/indieauth-now-...

Oh, thanks for reminding. I was told this before, but forgot.

I like it. What are the file formats that it can it import? I tried a .gpx file and it worked nicely.

Click the "Export" button, there will be a list. Basically, almost all of those: https://github.com/MapBBCode/share.mapbbcode.org/tree/master... (except html, iframe, nmea).

Nice service indeed, I like it more than anything I tried before.
