Table 6.79—DRM_EC_Location_2D

Property

Description

Superclass

·         <DRM Location 2D>

Class

·         <DRM EC Location 2D>

Subclass

·         none

Definition

An instance of this DRM class specifies a coordinate within the Equidistant Cylindrical (EC) 2D spatial reference frame (SRF).

See [I18026] for a complete definition.

Example(s)

·         Consider a SEDRIS transmittal constructed from a MultiGen OpenFlight database. The transmittal contains a <DRM Environment Root> whose ORM is MultiGen Flat Earth, so its srf_parameters field is specified in Equidistant Cylindrical with horizontal_datum = SPHERICAL_MFE_HDATUM and vertical_datum = SPHERICAL_MFE_VDATUM (MultiGen "flat Earth" horizontal and vertical datums).

A <DRM EC Location 2D> within this spatial reference frame might be x = 30,0, y = 50,0.
