Returns the length of the linear parts of the geometry. Polygonal parts are ignored. The length of multi geometries is the sum of the lengths of their components.
Usage | Returns |
---|---|
MultiPolygon.length(maxError, proj) | Float |
Argument | Type | Details |
---|---|---|
this: geometry | Geometry | The input geometry. |
maxError | ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
proj | Projection, default: null | If specified, the result will be in the units of the coordinate system of this projection. Otherwise it will be in meters. |

// Define a MultiPolygon object. var multiPolygon = ee.Geometry.MultiPolygon( [[[[-122.092, 37.424], [-122.086, 37.418], [-122.079, 37.425], [-122.085, 37.423]]], [[[-122.081, 37.417], [-122.086, 37.421], [-122.089, 37.416]]]]); // Apply the length method to the MultiPolygon object. var multiPolygonLength = multiPolygon.length(); // Print the result to the console. print('multiPolygon.length(...) =', multiPolygonLength); // Display relevant geometries on the map. Map.setCenter(-122.085, 37.422, 15); Map.addLayer(multiPolygon, {'color': 'black'}, 'Geometry [black]: multiPolygon');
