Parameter Name |
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 |
The false easting to be applied to all X coordinates, selected to cause all X coordinates within the coordinate system to be positive values of reasonable size. |
|
Y_OFF |
The false northing to be applied to all Y coordinates. |
