• Press to select the desired transformation method
and set the corresponding parameters for each method:
- If the you know the coordinates of a point in both
coordinate systems (Grid and Ground) and also the rotation
of these systems, then, to find the relation between the Grid
to Ground coordinate systems, click the Ground Origin radio
button in the Grid - Ground window:
This method calculates an offset vector in the horizontal plane
between coordinates of a point (let’s call this point the origin
point) in the grid and ground coordinate systems and, using this
offset, computes the ground coordinates from the grid
coordinates. If a rotation angle is present between these
coordinate systems, the application can rotate a grid or ground
coordinate system relative to this point. Also MAGNET Tools
takes into account a scale factor between these coordinate
systems:
-After determining the relation between both coordinate systems,
the application will recalculate ground coordinates from the grid
