ee.Geometry.Rectangle.bounds
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
返回几何图形的边界矩形。
用法 | 返回 |
---|
Rectangle.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。 |
maxError | ErrorMargin,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 Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);
// Apply the bounds method to the Rectangle object.
var rectangleBounds = rectangle.bounds();
// Print the result to the console.
print('rectangle.bounds(...) =', rectangleBounds);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(rectangle,
{'color': 'black'},
'Geometry [black]: rectangle');
Map.addLayer(rectangleBounds,
{'color': 'red'},
'Result [red]: rectangle.bounds');
