ee.Feature.length
Returns the length of the linear parts of the geometry of a given feature. Polygonal parts are ignored. The length of multi geometries is the sum of the lengths of their components.
| Usage | Returns |
|---|
Feature.length(maxError, proj) | Float |
| Argument | Type | Details |
|---|
this: feature | Element | The feature from which the geometry is taken. |
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. |

It returns a float value representing this length. The method accepts optional `maxError` and `proj` arguments. `maxError` defines the acceptable error during reprojection, and `proj` specifies the desired coordinate system for the output, defaulting to meters if unspecified.
