ee.Geometry.LineString.toGeoJSONString

  • The toGeoJSONString() method returns a GeoJSON string representation of a geometry.

  • It can be applied to a LineString object and returns a String.

  • The method takes the Geometry instance as an argument.

  • Examples are provided in both JavaScript and Python demonstrating its usage and the resulting output.

  • The content also includes information on setting up the Python environment for interactive development with geemap.

Returns a GeoJSON string representation of the geometry.

Examples

Code Editor (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');
