範例
程式碼編輯器 (JavaScript)
// Define a MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);
// Apply the projection method to the MultiPoint object.
var multiPointProjection = multiPoint.projection();
// Print the result to the console.
print('multiPoint.projection(...) =', multiPointProjection);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPoint,
{'color': 'black'},
'Geometry [black]: multiPoint');

[null,null,["上次更新時間:2025-07-26 (世界標準時間)。"],[],["The `projection()` method is applied to a `MultiPoint` geometry object to retrieve its projection. This method requires a `Geometry` object as an argument. In both JavaScript and Python examples, a `MultiPoint` is created. Subsequently, `projection()` is called on it, storing the returned `Projection`. The code then prints the `Projection`. Finally, a map is centered and a layer is added, visualizing the `MultiPoint` geometry. The result type for the function is a `Projection`.\n"]]
