isInverse

True if this geographic transformation step instance is an inverted transformation. Transformations have a specific direction that is indicated by the GeographicTransformationStep.wkText value. An inverted transformation is used to transform geometries in the opposite direction to that indicated by the well-known text. GeographicTransformation has DatumTransformation.inputSpatialReference and DatumTransformation.outputSpatialReference properties that respect the inverse value of the contained transformation(s).

This API supports a large number of transformation WKIDs, including transformations from every supported datum to the World Geodetic System 1984 (WGS84) datum. To transform coordinates between two non-WGS84 datums, typically one forward and one inverse GeographicTransformationStep are added to a GeographicTransformation, to get the required inputs and outputs.
