    Geometry standardize

    Supported in: Batch, Streaming

    Given a valid geometry, standardizes it by enforcing the right-hand rule on the input, which is the convention for GeoJSON. This enables equality comparisons between equivalent geometries. This expression may reverse linestrings.

    Expression categories: Geospatial

    Declared arguments

    • Expression - Geometry to be standardized.
      Expression<Geometry>

    Output type: Geometry

    Examples

    Example 1: Base case
