+This coordinate system is a geographically referenced, local 3-D Cartesian
+ coordinate system.
+ This allow use of a conventional Cartesian coordinate system with accurate
+ georeferencing.
+ For example, one can construct a finite-element model in this coordinate
+ system and use spatial databases in geographic coordinates.
+ This coordinate system provides an alternative to using a geographic projection
+ as the Cartesian grip.
+ The advantage of this coordinate system is that it retains the curvature
+ of the Earth, while a geographic projection does not.
