For the restoration of the pre-industrial building "fabrika" and turning a center of projection
and promotion of agricultural production and trade by sea in historic place leonidion, development parnonas.
That is why this study assumes a single center of projection corresponding to the entrance pupil point for 0 = 0[degrees] (center of the semi-circle setup).
This new mapping function, which assumes a single center of projection as explained in Section 3.
0]) is the center of projection and p is a rotation about the radius vector to the center of projection.
The map is circular, and the antipodal point of the center of projection is a singular point which maps to the circular limb; hence, all that is needed is to place this point in the ocean (as in Figure 1).
