Table 6.271—DRM_Spatial_Resolution_Level_Of_Detail_Data

Property

Description

Superclass

·         <DRM Base Level Of Detail Data>

Class

·         <DRM Spatial Resolution Level Of Detail Data>

Subclass

·         none

Definition

An object of this DRM class specifies the spatial resolution of the associated data, which governs the switching of objects by a spatial-resolution-based <DRM Level Of Detail Related Geometry> or <DRM Level Of Detail Related Features> object.

Example(s)

·         NIMA DTED is produced at a number of standard spatial resolutions: 30 arc seconds, 3 arc seconds, 1 arc second, 0.3 arc second, and so on. Although the spatial resolution of the longitudinal axis varies with latitude, the spatial resolution of the latitudinal axis is fixed (and equals that of the longitudinal axis at the equator).

·         Atmospheric data sets are often produced in an Augmented Projection-based Spatial Reference Frame, such as ALCC (Augmented Lambert Conformal Conic), at a number of standard spatial resolutions; e.g., 81 kilometers, 27 kilometers, and 9 kilometers.
