C-MAP Electronic charts are produced using official Hydrographic Office (HO) charts under the controls of ISO 9002 certified quality system. They are accurate to the best of C-Map's knowledge and any inconsistencies found are generally due to undetectable limitations in the HO charts themselves. C-MAP electronic charts are not currently considered legal replacements of official HO charts and so should be used only as supplements to these, together with prudent navigation habits. Where due, Royalty Charges are included in C-CARD prices and paid to National Hydrographic Authorities.
