Resumen

How precise is the portrayal of information on Canadian charts? When and how are errors introduced during the chart construction process? What is the magnitude of these errors? This paper will attempt to answer these questions. The evaluation is based on a production path which includes computer-assisted cartographic techniques. For a proper evaluation, it will be necessary to examine the subject matter in three stages: Stage One deals with the accuracy of the ‘Source D ata’. This paper deals mainly with Stage Two, which will cover all cartographic and chart production activities from the time the cartographer receives the source documents to the point where the chart is printed and released. Stage Three involves the nautical chart user. The goal, in that case, would be to establish what degree of accuracy the user needs and expects.
