ST_SimplifyPreserveTopology

case class ST_SimplifyPreserveTopology(inputExpressions: Seq[Expression]) extends InferredBinaryExpression[Geometry, Double, Geometry] with FoldableExpression with Product with Serializable

Simplifies a geometry and ensures that the result is a valid geometry having the same dimension and number of components as the input, and with the components having the same topological relationship. The simplification uses a maximum-distance difference algorithm similar to the Douglas-Peucker algorithm.

inputExpressions

first arg is geometry second arg is distance tolerance for the simplification(all vertices in the simplified geometry will be within this distance of the original geometry)
