QGIS 3'te seçilen bir özellik WKT'yi almanın bir yolu var mı?

QGIS 2.x'te , seçilen bir özelliğin WKT'sini almak için getWkt eklentisini kullandım : https://github.com/hugoledoux/QGIS-getWKT .

Ancak bu eklenti QGIS 3.x'te mevcut değildir. Bu özellik çekirdek QGIS 3'te yerleşik miydi? Yoksa bu eklentinin yetişmesini beklediğimiz bir durum mu?

Her zaman getWKT eklentisini kullandığımdan bu durumun aslında QGIS 2.x'in bir parçası olup olmadığından emin değilim. Ancak WKT'ye Tanımla penceresi bağlam menüsünden erişilebilir:

Bu nedenle, GeoJson olarak ayarlanmışsa veya geometri yoksa, WKT'yi almak için ikincil bir seçenek kullanmanız gerekir (bu sorunun diğer yanıtlarına bakın).

Bunun ihtiyaçlarınızı karşılayıp karşılamadığından emin değilsiniz, ancak aşağıdakileri içeren bir sanal katman ekleyerek WKT'yi alan hesap makinesinden alabilirsiniz (ve her zaman elde edebilirsiniz):

geomToWKT( $geometry )

Python Konsolunda aşağıdakileri de kullanabilirsiniz (yönteminiz daha hızlı olsa da):

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

Bazı özelliklerin seçilmesiyle kopyala veya Ctrl + c tuşlarını kullanarak özellikleri kopyalayabilirsiniz.

Ardından bir e-tablo sayfasına veya not defterine yapıştırabilirsiniz. Geometri sütunu WKT'de temsil edilecektir.

Daha önce sözü edilen ifadeyle bir alan (sanal veya değil) oluşturmak gibi WKT almanın birçok yolu vardır.

Ancak QuickWKT ile ilgili orijinal sorunuz için bu eklenti QGIS 3'e taşınmıştır. Eklenti yöneticinizi kontrol edin.
