Restituisce l'intersezione delle due geometrie.
Utilizzo | Resi |
---|
MultiLineString.intersection(right, maxError, proj) | Geometria |
Argomento | Tipo | Dettagli |
---|
questo: left | Geometria | La geometria utilizzata come operando sinistro dell'operazione. |
right | Geometria | La geometria utilizzata come operando destro dell'operazione. |
maxError | ErrorMargin, valore predefinito: null | La quantità massima di errore tollerata durante l'esecuzione di qualsiasi riproiezione necessaria. |
proj | Proiezione, valore predefinito: null | La proiezione in cui eseguire l'operazione. Se non specificato, l'operazione verrà eseguita in un sistema di coordinate sferiche e le distanze lineari saranno in metri sulla sfera. |
