Description

Class
  • <DRM World Transformation>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class is a <DRM Transformation>, specified by a <DRM Location> and a <DRM World 3x3>, used to transform an object defined in an LSR spatial reference frame into another spatial reference frame (usually, but not always, a non-LSR spatial reference frame).

A <DRM World Transformation> is either

  • defined in a non-LSR spatial reference frame, then used to instance an LSR <DRM Model> into the non-LSR spatial reference frame, or
  • defined within an LSR spatial reference frame (SRF_1), and then used to instance a <DRM Model> embedded within another LSR spatial reference frame (SRF_2) into SRF_1, in a way that maintains the conformality of any <DRM Location> instances in the <DRM Model>.

Example(s)

  • Used when instancing a house onto geodetic terrain (defined by latitude and longitude). This allows the <DRM Location> to position the house and the <DRM World 3x3> to rotate and scale the house.

  • The location, and orientation of a grid defining a liquid water content layer referenced to the terrain.

  • See <DRM Transformation> for examples.
