ee.Feature.perimeter
Returns the length of the perimeter of the polygonal parts of the geometry of a given feature. The perimeter of multi geometries is the sum of the perimeters of their components.
| Usage | Returns | Feature.perimeter(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. |
