ee.Geometry.LineString.toGeoJSONString

返回几何图形的 GeoJSON 字符串表示形式。

用法返回
LineString.toGeoJSONString()字符串
参数类型详细信息
此：geometry几何图形Geometry 实例。

示例

代码编辑器 (JavaScript)

// Define a LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);

// Apply the toGeoJSONString method to the LineString object.
var lineStringToGeoJSONString = lineString.toGeoJSONString();

// Print the result to the console.
print('lineString.toGeoJSONString(...) =', lineStringToGeoJSONString);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(lineString,
             {'color': 'black'},
             'Geometry [black]: lineString');
