ee.Geometry.LinearRing.intersects

：如果幾何體相交，則傳回 true，否則傳回 false。

用量傳回
LinearRing.intersects(right, maxError, proj)布林值
引數類型詳細資料
這個：left幾何圖形做為運算左運算元的幾何圖形。
right幾何圖形用做運算右運算元的幾何圖形。
maxErrorErrorMargin，預設值：null執行任何必要重投影時可容許的最大誤差量。
proj投影，預設值：null執行作業的投影。如未指定，系統會以球面座標系統執行作業，而球面上的線性距離會以公尺為單位。

範例

程式碼編輯器 (JavaScript)

// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the intersects method to the LinearRing object.
var linearRingIntersects = linearRing.intersects({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('linearRing.intersects(...) =', linearRingIntersects);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(linearRing,
             {'color': 'black'},
             'Geometry [black]: linearRing');
Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
