Official and Unofficial Chart Data
Chart formats may be classified as Official or Unofficial chart data.
Official chart data is known as ENC data. All official chart data must comply
with data standards set by members of the IHO and published in their
document S-57, Edition 3.
An unofficial chart format is data which does not comply with the S-57
Edition 3 document (e.g. SevenCs World Map).
An Unofficial Data permanent prompt is displayed whenever chart data
from a unofficial source is displayed. Unofficial data is not certified for safe
navigational and the operator should refer to paper charts for unofficial data
regions.
