umscnt

12.2.1 umscnt

1.

Function

Specifies the "contact" of the plane of projection.

2.

Call

NumRu::DCL.umscnt(xcnt,ycnt,rot)

3.

Explanation of Parameters

uxc,uyc (R) The longitude and latitude of the contact.

rot (R) The inclination of the central meridian. (clockwise)

4.

Notes

(a): This information is used by UMPFIT.
(b): In a normal cylindrical projection (normal aspect), UYC=0 and rot=0. Otherwise, it is in an oblique aspect.
(c): In a conical projection, uyc becomes the standard meridian unless the standard meridian (STLAT1) is specified. When the standard meridian is specified, a cone corresponding to it is set, and the cone is inclined so that it comes into contact at (UXC, UYC). Such a projection is in an oblique aspect.
(d): In the azimuthal projection, (UXC,UYC,ROT) is synonymous with the pole of the map projection (PLX,PLY,PLROT).

`uxc,uyc`	`(R)`	The longitude and latitude of the contact.
`rot`	`(R)`	The inclination of the central meridian. (clockwise)
