Existe-t-il un moyen dans QGIS 3 d'obtenir une fonctionnalité sélectionnée WKT?

Dans QGIS 2.x, j'ai utilisé le plugin getWkt : https://github.com/hugoledoux/QGIS-getWKT pour obtenir un WKT d'une fonctionnalité sélectionnée.

Mais ce plugin n'est pas présent dans QGIS 3.x. Cette capacité a-t-elle été intégrée au cœur de QGIS 3? Ou est-ce un cas où nous attendons que le plugin rattrape son retard?

Je ne sais pas si cela faisait réellement partie de QGIS 2.x car j'ai toujours utilisé le plugin getWKT. Mais le WKT est accessible depuis le menu contextuel de la fenêtre Identifier:

Le comportement de la fonction de copie peut être modifié dans Options | Data Sources | Feature attributes and table | Copy features as:

Donc, si cela est défini sur GeoJson ou aucune géométrie, vous devez utiliser une option secondaire pour obtenir le WKT (voir les autres réponses à cette question).

Je ne sais pas si cela répond à vos besoins, mais vous pouvez (et pourriez toujours) obtenir le WKT à partir de la calculatrice de terrain en ajoutant une couche virtuelle avec:

geomToWKT( $geometry )

Vous pouvez également utiliser les éléments suivants dans la console Python (bien que votre méthode soit plus rapide):

layer = iface.activeLayer()
for feat in layer.selectedFeatures():
    print(feat.geometry().asWkt())

Après avoir sélectionné certaines fonctionnalités, vous pouvez simplement copier les fonctionnalités à l'aide du bouton Copier ou Ctrl + c.

Ensuite, vous pouvez coller sur une feuille de calcul ou un bloc-notes. La colonne de géométrie sera représentée en WKT.

Il existe de nombreuses façons d'obtenir WKT, comme la création d'un champ (virtuel ou non) avec l'expression mentionnée précédemment.

Mais pour votre question d'origine sur QuickWKT, ce plugin a été porté sur QGIS 3. Vérifiez votre gestionnaire de plugins.
