ee.Geometry.BBox.geodesic
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
如果為 false，投影畫面邊緣會是直線。如果是 true，邊緣會彎曲，以遵循地球表面的最短路徑。
範例
程式碼編輯器 (JavaScript)
// Define a BBox object.
var bBox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43);
// Apply the geodesic method to the BBox object.
var bBoxGeodesic = bBox.geodesic();
// Print the result to the console.
print('bBox.geodesic(...) =', bBoxGeodesic);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(bBox,
{'color': 'black'},
'Geometry [black]: bBox');
