I have a small script that I'm using to generate GeoJSON data from a data format not currently supported by GIS software.

I would like to validate the output, but when I use ogr2ogr to read it, it doesn't give me any helpful information about what aspects, lines, or characters contained invalid data.

Is there a decent GeoJSON validator somewhere, or a good method of validating GeoJSON data with OGR?

EDIT: I am not looking for JSON validators or the GeoJSON spec. I've seen and used both to get to this point, but OGR still returns an error.

I have explained it before in this post.

The differences between JSON and GeoJSON are all about spelling. You can add more definition if you want. I don't think it is very important if you do not take part in the JSON spec for GeoJSON... there is no limit for a JSON object; the only important thing is that your JSON must be valid for correct usage.

You can check whether or not your GeoJSON file is valid with JSONLint which is a JSON Validator...

and you can check against the GeoJSON spec here.

I hope this helps you.

The GeoJSON spec is at - you linked to GeoJSON CSS, an unofficial extension. – tmcw Sep 17 '12 at 0:14
