AEC Location 3D

Class Name: AEC Location 3D

Superclass - <Location 3D>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a coordinate within the Augmented Equidistant Cylindrical (AEC) 3D Spatial Reference Frame (SRF).

See [I18026] for a complete definition.

Example

  1. Consider a SEDRIS transmittal constructed from a MultiGen OpenFlight database. The transmittal contains an <Environment Root> instance ER, the ORM of which is MultiGen Flat Earth, such that the srf_parameters field of ER is specified in Augmented Equidistant Cylindrical with the Multigen "flat Earth" horizontal and vertical datums, SRM_HDATUM_SPHERICAL_MFE and SRM_VDATUM_SPHERICAL_MFE.

    An <AEC Location 3D> within this spatial reference frame might be x = 30.0, y = 50.0, z = 100.0.
