範例
程式碼編輯器 (JavaScript)
// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);
// Apply the projection method to the Point object.
var pointProjection = point.projection();
// Print the result to the console.
print('point.projection(...) =', pointProjection);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(point,
{'color': 'black'},
'Geometry [black]: point');
