Definition

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

A <World Transformation> instance is either

• defined in a non-LSR SRF, then used to instance an LSR <Model> instance into the non-LSR SRF, or
• defined within an LSR SRF (SRF₁), and then used to instance a <Model> embedded within another LSR SRF (SRF₂) into SRF₁, in a way that maintains the conformality of any <Location> instances in the <Model> instance.

Example

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

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

3. See <Transformation> for examples.
