Abstract

As in so many other fields of work, which have used traditional manual methods for many years, the use of automatic data handling methods and computers is bringing about changes in hydrographic work. This description is particularly concerned with automatic methods of reading and drawing — in other words, the analysis of charts and traces and the production of charts or line drawings. In general, the latter can be carried out completely automatically, but the reading of information normally requires the discretion and assistance of an operator. However, new methods of the recording of basic information are now being developed to make the collection and analysis of information also completely automatic.
