Template-info.png Dokumentacja modułu [zobacz] [edytuj] [historia] [odśwież]

Dedykowana uniwersalna wtyczka formatująca wartość cechy ze współrzędnymi geograficznymi.

Wtyczka obsługuje parametr linkuj oraz parametr format, który przyjmując jedną z wartości kątowo lub dziesiętnie pozwala zawęzić sposób prezentacji współrzędnych.
