About ENC Charts
An ENC chart is a vector based chart format that can be displayed using your
marine navigaion software. NOAA and the Army Corps of Engineers provide
offshore and inland waterway ENC's for all of the United States. Although
charts in the intenational s-57 standard are called ENC, the international
standard for this format is designated s-57.
