Chart Correction Techniques, Continued

Time Saver: When correcting charts that have accumulated numerous
corrections, it is more practical to make the latest correction first and
work backwards since later corrections may cancel or alter earlier
corrections. Remember to use the Summary of Corrections.
Chartlet corrections (pasters) appearing in the back of section I of the
Notice to Mariners are to be affixed to the chart in the proper area.
They must be glued in place.
Any outstanding temporary changes must
be transferred to the chartlet. Temporary changes in Aids to Navigation
are not plotted by the DMA. It may be necessary to pen in lengthy
notes on a chart. It is desirable to photocopy the note from the NTM
and paste it on the chart whenever possible.
