public class TLcdKrovak extends ALcdProjection implements Cloneable
A krovak projection is an oblique conic map projection. It superimposes a cone over the sphere of the Earth, with the axis through a defined location, and cutting the ellipsoid minor axis at a defined angle.
true
along the pseudo standard parallel,
which forms a complex curve on the ellipsoid.
TLcdKrovak projection = new TLcdKrovak(42.5, 49.5, 0.28813972222222, 78.5);
The equations of the krovak projection are based on the epsg guidance note 7, part 2
