示例
代码编辑器 (JavaScript)
// Define a MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);
// Apply the toGeoJSON method to the MultiPoint object.
var multiPointToGeoJSON = multiPoint.toGeoJSON();
// Print the result to the console.
print('multiPoint.toGeoJSON(...) =', multiPointToGeoJSON);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPoint,
{'color': 'black'},
'Geometry [black]: multiPoint');
