Vertical grid shift transformation

Description

Models with spatial domain can be transformed by applying a vertical grid shift to transition between different vertical datums. This transformation is governed by two parameters:

• grids: A list of grids to be applied. The available grids are sourced from Natural Resources Canada and the US National Geospatial-Intelligence Agency.
• multiplier: (Optional) Specify the multiplier to apply to the grid value in the forward transformation direction. Note that the default is -1.0 for historical reasons.
