HOM2UV: Hotine Oblique Mercator – Two Points, Unrectified

This variation of Hotine produces unrectified Cartesian coordinates. Its origin is the intersection of the central geodesic and the equator of the aposhere. Although it is rarely used, it is retained for historical purposes.

Parameter Name

Description

PARM1

The longitude, in degrees, of the first point on the central geodesic.

PARM2

The latitude, in degrees, of the first point on the central geodesic.

PARM3

The longitude, in degrees, of the second point on the central geodesic.

PARM4

The latitude, in degrees, of the second point on the central geodesic.

ORG_LAT

The latitude, in degrees, of the center of the coordinate system being defined. That is, the point on the central geodesic that has this latitude is the natural origin of the projection.

X_OFF

The false easting to be applied to all X coordinates, usually 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.
