示例
代码编辑器 (JavaScript)
// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);
// Apply the toGeoJSONString method to the Point object.
var pointToGeoJSONString = point.toGeoJSONString();
// Print the result to the console.
print('point.toGeoJSONString(...) =', pointToGeoJSONString);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(point,
{'color': 'black'},
'Geometry [black]: point');
