Clarifications

1The first <DRM Location> component is the minimum or lower left corner. In the case of a 3D <DRM Spatial Extent> instance, the z/elevation value of this <DRM Location> component is the minimum elevation of the bounding volume being specified, rather than the elevation at the lower left corner.

The second <DRM Location> component is the maximum or upper right corner. In the case of a 3D <DRM Spatial Extent> instance, the z/elevation value of this <DRM Location> component is the maximum elevation of the bounding volume being specified, rather than the elevation at the upper right corner.

Example(s)

  • The spatial extent of a <DRM Environment Root> instance within a transmittal, defined by the minimum and maximum latitude and longitude values (that is, the southwest and northeast corners).

  • The bounding parallelepiped of a <DRM Model> instance representing a building, in LSR coordinates.
