Requete WFS Parcelle IGN

**ggenard** · 29/01/2016, 17h41

Bonjour,

J'essaie en vain d'effectuer une requête au près du service WFS Parcelle de l'IGN en POST...
Les droits sont bien inclus avec la clef puisque la requête en GET fonctionne, cependant je dois effectuer un intersects qui est beaucoup trop long pour être effectué en GET.

Le XML passé en post est en pièce jointe et est envoyé sur l'adresse suivante: http://wxs.ign.fr/CLE/geoportail/wfs?

J'obtiens la réponse suivante:
<?xml version="1.0" encoding="UTF-8"?>
<ows:ExceptionReport version="2.0.0"
xsi:schemaLocation="http://www.opengis.net/ows/1.1 http://wxs.ign.fr/geoportail/schemas/ows/1.1.0/owsAll.xsd"

<ows:Exception exceptionCode="NoApplicableCode">
<ows:ExceptionText>java.lang.NullPointerException
null</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

Merci de m'éclairé...

Cordialement.

Bonsoir,

En effet, le fait d'utiliser une géométrie complexe (gml : MultiPolygon) pour l'intersection dans la requête semble ne pas être apprécié par le serveur, qui renvoie une erreur.

En revanche, en utilisant une requête avec un gml : Polygon simple, la requête aboutit. Par exemple : (requête basée sur la votre)

Si cela vous convient, vous pouvez essayer d'envoyer plusieurs requêtes, avec des géométries simples d'intersections (comme le polygone ci-dessus).

Bonjour,

Merci pour cette réponse.
Malheureusement en vu du nombre de polygones, nous ne pouvons pas effectuer une requête par polygone...

Cordialement.

En fait, gml:MultiPolygon n'est simplement pas implémenté dans la version GML (3.2.1) supportée par le serveur.
Il faut utiliser plutôt des multi surfaces (gml:MultiSurface) pour intersecter une géométrie multiple. La syntaxe est légèrement différente.

Par exemple, la requête suivante marche : (adaptation de votre requête)

Je vous laisse regarder le schéma de définition xml d'une balise MultiSurface pour GML 3.2.1 pour plus de détails : http://schemas.opengis.net/gml/3.2.1...Aggregates.xsd.

J'espère que cela résoudra votre problème

Bonne journée !
