ee.Geometry.LinearRing.bounds

返回几何图形的边界矩形。

用法返回
LinearRing.bounds(maxError, proj)几何图形
参数类型详细信息
此：geometry几何图形返回相应几何图形的边界框。
maxErrorErrorMargin，默认值：null执行任何必要的重新投影时可容忍的最大误差量。
proj投影，默认值：null如果指定了此参数，结果将采用此投影。否则，它将采用 EPSG:4326。

示例

代码编辑器 (JavaScript)

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

// Apply the bounds method to the LinearRing object.
var linearRingBounds = linearRing.bounds();

// Print the result to the console.
print('linearRing.bounds(...) =', linearRingBounds);

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