> "CLARIFICATION CONCERNING THE USE OF TERRAIN DATA IN MOVING MAP
DISPLAYS:
>
> Terrain data are currently available and can easily be incorporated into
> moving map displays. However, existing terrain data is not accurate and
can
> be seriously misleading. The problem is further exacerbated by GPS error
> introduced by the military. Because of the errors, most moving map
display
> manufacturers have prudently decided to delay displaying the terrain
data
> until it is reliable.
>
> Among these manufacturers, Archangel is one of the companies selected by
> NASA to help correct the data presentation problems and develop reliable
synthetic vision displays.
The corrections are expected to be completed next year. At that time
3-D terrain will be
> included on Archangel and other moving map displays."
