Frame for 3-D map display
This map display is not a true map projection. It is constructed by calculating a three-dimensional frame and displaying the map objects on the surface of this frame.
In the three-dimensional sense, globe is true in scale, equal-area,
conformal, minimum error, and equidistant everywhere. When displayed,
however, it looks like an Orthographic azimuthal projection, provided
that the MATLAB® axes
is set to
The globe requires no standard parallels.
This is the only three-dimensional representation provided for display. Unless some other display purpose requires three dimensions, the Orthographic projection's display is equivalent.
