On the automatic data acquisition and processing system for ocean survey.

Abstract

In promoting automation of hydrographic services, the following three items can be considered as main projects: (1) Automatic data acquisition and processing system on board a survey vessel. (2) Survey data filing. (3) Automatic drawing and compilation of survey results. During the course of the "Research on Automatic Drawing" carried out for three years from the fiscal year 1970, a concrete progress has been made in the researches and studies which have mainly been focused on the item (1) above. As the result, a system devised is now put to practical use in gravity measurements at sea. It is now. promising that another system developed will also be put to practical use in the real-time processing of ship’s position by Loran C system. It is considered that the completion of the automatic data acquisition and processing system will necessarily lead the ways and means to developing the systems for items (2) and (3) above. In this paper the authors report the outline of the researches, studies and results concerning the automatic data acquisition and processing system for ocean survey.
