OrthographicΒΆ
This is a perspective projection like the general perspective, but with the difference that the point of perspective lies in infinite distance. It is therefore often used to give the appearance of a globe viewed from outer space, were one hemisphere can be seen as a whole. It is neither conformal nor equal-area and the distortion increases near the edges.
glon0/lat0[/horizon]/scale
or Glon0/lat0[/horizon]/width
lon0/lat0
specifies the projection center, the optional parameter horizon
specifies the max distance from projection center (in degrees, <= 90, default 90)
