Applying corrections to these are going to be next to impossible especially since they don’t put out change history for ENCs like they do the paper charts, this will be nice for… Wall art. NMs only reference chart numbers. Changes wont show up on charts that don’t exist anymore.
The NOAA custom chart generator seems to be the logical answer, but since SE Alaska lost half their harbor charts yesterday, I’m just wondering if there is guidance from the NMC or States on parameters for generating the charts to study for pilotage.
