  18. After Translation

  19. Integration • Existing points are regenerated from the GSDA database • Common points are matched and a least squares adjustment is performed • Adjusted points are written to the database.

  20. Plan Input • Geomatics cartographer checks out the affected section • Affected line work identified and updated • New line work is added
