coordinate system and vice versa. See Creating a ground
projection relative to a point.
- If the you know the value of the scale factor between grid and
ground coordinate systems or the average height of the network,
then to find the relation between Grid to Ground coordinate
systems, click the Parameters radio button in the Grid-> Ground
dialog window:
This method calculates plane ground coordinates by scaling,
offsetting, and rotation of grid coordinates. If a rotation angle is
present between these coordinate systems, the application can
rotate the ground coordinate system relative to the origin of the
Grid coordinate system (centre of the projection).
