ee.Geometry.MultiLineString.bounds

返回几何图形的边界矩形。

用法返回
MultiLineString.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 MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

// Apply the bounds method to the MultiLineString object.
var multiLineStringBounds = multiLineString.bounds();

// Print the result to the console.
print('multiLineString.bounds(...) =', multiLineStringBounds);

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