UCT,UG4,APT: Add Point for Grid Transformation
$PASHS,UCT,UG4,APT,f1,f2,f3,f4,f5,f6,f7,f8
This commands adds a point for the estimation of grid to grid transformation
parameters where Table 6.63 outlines the parameters. You must enter this
command for each of the four required data points to compute the grid to grid
transformation parameters.
UCT,UG4,CAL: Calculate Grid Transformation Parameters
$PASHS,UCT,UG4,CAL
This command computes the estimated grid transformation parameters for the
user-defined grid. In order to compute the estimated grid transformation
parameters, you must have entered the four data points with the
$PASHS,UCT,UG4,APT command.
$PASHQ,UCT,UG4,CAL
This command queries for the estimated grid to grid transformation parameters.
