Resumen

Since the late nineteen sixties, the Canadian Hydrographic Service (CHS) has been actively pursuing the goal of acquiring and processing bathymetric data in digital form. During this period there have been major advances in digital technology and to a large extent the CHS has been able to take advantage of this evolving technology. Over the years a core of computer-oriented hydrographers and hydrography-oriented technical personnel has been developed and we have enjoyed patient and supportive managers with whom new ideas and techniques could be openly and critically discussed. Numerous problems have been encountered - some have been overcome while others remain to be solved. In the main, however, reliable digital data acquisition and processing in the field at a reasonable cost is feasible. The means to convert graphical data such as shoreline and foreshore features into digital form is also in place so that we are finally in a position to start building a digital data base from which nautical charts may be produced.
