Name Description
LaDInDegrees Latitude in degrees at which the Mercator Projection Cylinder Intersects the Earth. Latitude in degrees where Dx and Dy are specified
Latin
LoVInDegrees orientation of the grid; i.e. the east longitude value of the meridian which is parallel to the y-axis (or columns of the grid) along which latitude increases as the y-coordinate increases (the orientation longitude may or may not appear on a particular grid)
Ni Number of points along a parallel
Nj Number of points along a meridian
alternativeRowScanning Alternative row of scanning
angleOfRotationInDegrees Angle of rotation in degrees
