public class TLcdPolyconic extends ALcdProjection
Conical projection. The projection stems from "rolling" a cone tangent to the Earth at all parallels of latitude, instead of a single cone in a normal conic projection.
true
along each parallel and along the central meridian.
ILcdProjection projection =
new TLcdPolyconic(0.0, 0.0);
The equations of the polyconic projection are taken from [Snyder1987].
