GeoJSON is not properly formatted

[kofronpi]

GeoJSON returned by the server is invalid and does not pass lint tests on /france/v1/polygon when specifying a geojson serializer.

Line 7: the first and last positions in a LinearRing of coordinates must be the same Line 75: the first and last positions in a LinearRing of coordinates must be the same Line 359: the first and last positions in a LinearRing of coordinates must be the same Line 659: the first and last positions in a LinearRing of coordinates must be the same Line 1123: the first and last positions in a LinearRing of coordinates must be the same Line 1351: the first and last positions in a LinearRing of coordinates must be the same Line 1395: the first and last positions in a LinearRing of coordinates must be the same Line 6703: the first and last positions in a LinearRing of coordinates must be the same [...]

Relevant spec from http://geojson.org/geojson-spec.html#polygon:

A LinearRing is closed LineString with 4 or more positions. The first and last positions are equivalent (they represent equivalent points). Though a LinearRing is not explicitly represented as a GeoJSON geometry type, it is referred to in the Polygon geometry type definition.

Is this still happening?

[kofronpi]

Yes, although with less warnings than before.

[gerbsen]

Could you please provide a request URL?

[kofronpi]

[gerbsen]

Where do you test the geojson?

[gerbsen]

Well probably here right? http://geojsonlint.com/

[kofronpi]

Yes but I also try to import it into PostGIS to visualize it with QGIS and it fails because of the incorrect format, I have to "clean it up" before.

[gerbsen]

Okay, this is very strange. We are performing this repair operation also on our servers. We will look into this error. Thanks for bringing it up.

[gerbsen]

@kofronpi we just release an improved version of the geojson feature. could you test it again?

[gerbsen]

@kofronpi I just saw that you provided an example request url. I was able to retrieve this with the new version and loaded in qgis. So I'm closing this for now. In case the error persists, just reopen the issue!

[kofronpi]

@gerbsen it seems to work fine for now. I'll tell you if I find any new bugs ! :+1: Did you guys change the area returned in the payload with this update ?

[gerbsen]

@kofronpi what exactly do you mean with "change the area"?
