Property

Description

Class
  • <DRM Spatial Resolution LOD Data>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class specifies the spatial resolution of the associated data, which governs the switching of objects by a spatial resolution based <DRM LOD Related Geometry> instance or <DRM LOD Related Features> instance.

The spatial_resolution field specifies the spatial resolution of the associated data and shall be a positive value.

The unit field specifies how the spatial resolution value is measured.

Example(s)

  • Consider a transmittal containing data imported from DTED. DTED is produced at a number of standard spatial resolutions such as 30 arc seconds, 3 arc seconds, 1 arc second, and 0,3 arc second. A <DRM Spatial Resolution LOD Data> link object specifies the spatial resolution of the data contained in the associated DRM object.

  • Sets of atmospheric environmental data are often produced in an SRF based on a map projection augmented SRFT (such as LCC_Augmented_3D) at a number of standard spatial resolutions such as 81 kilometres, 27 kilometres, and 9 kilometres. A <DRM Spatial Resolution LOD Data> link object specifies the spatial resolution of the data contained in the associated DRM object.
