case classST_SimplifyPreserveTopology(inputExpressions: Seq[Expression]) extends Expression with CodegenFallback 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)
