Résumé

This paper deals with the work of the International Hydrographic Organization (IHO) during the last ten years towards the standardization of nautical charts. The work began with the devising of a regional scheme of medium- and large-scale sheets of the north-east Atlantic area, to be coproduced by member nations as contributions to an International (INT) set of charts. It subsequently became clear that, as well as the scheme, a detailed set of specifications would be necessary to secure uniformity of choice of symbols and abbreviations throughout the International series, and also in the various national chart series of which it would form a part. The history of nautical chart standardization has recently been traced by Ritchie [1] — gradual at first after the beginning of the International Hydrographic Bureau in 1921, and later speeding up when the International Hydrographic Conference of 1967 established a study which led to two series of INT charts on very small scales. After this, the process gathered further speed with the successful establishment of the two bodies with whose work this paper is primarily concerned : the North Sea International Chart Commission (NSICC) in 1972 and the Chart Specifications (later Standardization) Committee (CSC) in 1977. The ten-nation NSICC, in drawing up the network of INT sheet-lines for its area, established the principles on which such schemes would be extended worldwide and also did extensive groundwork for the Chart Specifications of the IHO [2]. These were completed for worldwide application by the seventeen-nation CSC. The thinking behind these two fundamental aspects of nautical chart standardization — the chart scheme and the chart content — will be explored.
