Digital Mapping Charting, and Geodesy Analysis Program Technical Review: Digital Nautical Chart Product 1.

Abstract

The first production release of the Digital Nautical Chart (DNC) was a significant improvement over the previous prototypes. However, several key areas are still either incomplete or not addressed in the DNC. The Environment thematic layer still is not present in the DNC and environment data from the paper charts is omitted. DNC accuracies are not clearly stated. Feature labels do not follow the feature they describe, as on the paper charts. There is no standard symbology for the DNC, but there is one for the paper charts. The method of updating and correcting the DNC is not discussed. In addition, data errors between the product specification and the actual database are' noted. Issues raised by reviews of DNC prototypes 2 and 3, but not yet addressed, are restated. (MM)
