%Docstring(signature="appended")
|
|
Implementation of GeometrySimplifier using the Douglas-Peucker
|
|
algorithm.
|
|
|
|
Simplifies a geometry, ensuring that the result is a valid geometry
|
|
having the same dimension and number of components as the input. The
|
|
simplification uses a maximum distance difference algorithm similar to
|
|
the one used in the Douglas-Peucker algorithm.
