KROVAK: Oblique Conformal Conic for Czech and Slovak Republics

This an implementation of the Oblique Conformal Conic projection as is used in the Czech and Slovak republics where the system was devised.

Nom de paramètre

Description

PARM1

The longitude, in degrees, of oblique conic pole.

PARM2

The latitude, in degrees, of the oblique conic pole.

PARM3

Oblique Standard Parallel. This is the latitude of the standard par­allel of the oblique cone on the Gaussian surface.

Note  Only a single standard parallel is supported, but the effect of two standard parallels is achieved through the use of the scale reduction factor.

ORG_LNG

Origin longitude for the Oblique Conformal Conic projection. For the Krovak system, this is usually the meridian of Ferro: 17 39 59.735400W. An approximate value of 17 40 00.00W is often used.

ORG_LAT

Origin latitude for the Oblique Conformal Conic projection. This is usually 49 30 00N for the Krovakl systems.

X_OFF

Le faux Est doit être appliqué à toutes les coordonnées X, pour que toutes les coordonnées X dans le système de coordonnées aient des valeurs positives de taille raisonnable.

Y_OFF

Le faux Nord à appliquer à toutes les coordonnées Y.
