Conic projection based on one standard parallel. An azimuth parameter tilts the apex of the cone from the North Pole to create a new coordinate system. A standard parallel in the new system, called a pseudo standard parallel, defines the shape of the cone. A scale factor is applied to the pseudo standard parallel to create a secant case.
Two pseudo standard parallels.
Designed strictly for Czech Republic and Slovak Republic.
Used for topographic and other mapping in Czech Republic and Slovak Republic. The coordinates are usually positive to the south and west.
