AI-generated Key Takeaways
-
The
length()method returns the length of the linear parts of a geometry, ignoring polygonal parts. -
For multi geometries, the length is the sum of the lengths of their components.
-
The method can optionally take
maxErrorandprojarguments to control reprojection error tolerance and the output units. -
If no projection is specified, the result is returned in meters.
| Usage | Returns |

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 Point object. var point = ee . Geometry . Point ( - 122.082 , 37.42 ); // Apply the length method to the Point object. var pointLength = point . length (); // Print the result to the console. print ( 'point.length(...) =' , pointLength ); // Display relevant geometries on the map. Map . setCenter ( - 122.085 , 37.422 , 15 ); Map . addLayer ( point , { 'color' : 'black' }, 'Geometry [black]: point' );
