MicroStation PowerDraft CONNECT Edition Help


A projection commissioned by Rand McNally and Company in 1961 and created by A. H. Robinson. They wanted a new projection for its world maps with a view to minimizing area and angular distortion. It is neither conformal nor equal-area, but a compromise between the two. With this projection, more than 75% of the earth can be shown with less than 20% error from its true scaled size.

Note: This projection is supported in the spherical form only.
