A. You can use the Grid | Residuals command to calculate the Z value. Create a data file with the XY locations, and a column of 0’s that will be used for the zData values. Grid | Residuals subtracts zData – zGrid, so using a column of 0’s in the data file will return the negative of the Z value in the grid.
