ee.Geometry.bounds
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
傳回幾何的邊界矩形。
用量 | 傳回 |
---|
Geometry.bounds(maxError, proj) | 幾何圖形 |
引數 | 類型 | 詳細資料 |
---|
這個:geometry | 幾何圖形 | 傳回這個幾何圖形的周框。 |
maxError | ErrorMargin,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 | 如果指定,結果會以這個投影方式呈現。否則會採用 EPSG:4326。 |
範例

// Define a Geometry object.
var geometry = ee.Geometry({
'type': 'Polygon',
'coordinates':
[[[-122.081, 37.417],
[-122.086, 37.421],
[-122.084, 37.418],
[-122.089, 37.416]]]
});
// Apply the bounds method to the Geometry object.
var geometryBounds = geometry.bounds();
// Print the result to the console.
print('geometry.bounds(...) =', geometryBounds);
// Display relevant geometries on the map.

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