Navigation chart updating kit
Mariners using traditional paper charts apply chart corrections manually by using pencils, erasers, rulers, compasses, dividers, and protractors.Applying updates to a suite of paper charts can be time consuming, tedious, and error prone.NOAA has developed a paper product that addresses the problem of manual updates to paper charts.A POD chart is a paper chart that is printed at the time of purchase and contains chart updates up until the time of purchase.
The USCG LNM is published weekly by each of 9 individual Coast Guard Districts. In order for the mariner to transit safely, it is imperative that these changes be reflected on nautical charts as soon as practicable. Lawrence Seaway, the Canadian Coast Guard Notice to Mariners.
