Gibt „true“ zurück, wenn sich die Geometrien schneiden.
Nutzung | Ausgabe |
---|
Polygon.intersects(right, maxError, proj) | Boolesch |
Argument | Typ | Details |
---|
So gehts: left | Geometrie | Die Geometrie, die als linker Operand des Vorgangs verwendet wird. |
right | Geometrie | Die Geometrie, die als rechter Operand des Vorgangs verwendet wird. |
maxError | ErrorMargin, Standardwert: null | Die maximale Fehlergröße, die bei einer erforderlichen Rückprojektion toleriert wird. |
proj | Projektion, Standardwert: null | Die Projektion, in der der Vorgang ausgeführt werden soll. Wenn nichts angegeben ist, wird der Vorgang in einem sphärischen Koordinatensystem ausgeführt und lineare Entfernungen werden in Metern auf der Kugel angegeben. |

// Define a Polygon object.
var polygon = ee.Geometry.Polygon(

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);
// Apply the intersects method to the Polygon object.
var polygonIntersects = polygon.intersects({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('polygon.intersects(...) =', polygonIntersects);
// Display relevant geometries on the map.

Map.addLayer(polygon,
{'color': 'black'},
'Geometry [black]: polygon');
Map.addLayer(inputGeom,
