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.
