Restituisce l'intersezione delle due geometrie.
Utilizzo | Resi |
---|
Rectangle.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. |

Editor di codice (JavaScript)
// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);
// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);
// Apply the intersection method to the Rectangle object.
var rectangleIntersection = rectangle.intersection({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('rectangle.intersection(...) =', rectangleIntersection);
// Display relevant geometries on the map.
