摘要:This paper puts forward a novel concept of tetrahedron model of chart cartography error analysis and quality control which is necessary for introducing user to the former triangle model of error analysis and quality control, i.e. Reality-Producer-Chart-User. For the human being, high quality does not necessarily represent high accuracy, but represent a concept that what is fit for use. Classical cartography error theory coming from physics and mathematics will no longer meet the requirement of users, so the new concept deriving from communication and cognition sciences will compensate for the research. New model should adopt thought science which is from humanities. In tetrahedron model, producer refers to people who provide data, who manipulate data and who check data. User is considered as a quality controlling factor which has equal status with producer. Data quality control has changed from "Check-Driving" to "User-Driving". The words for quality assessment change from error or uncertainty to practicability or applicability. Reality here refers to ocean and coastal zone. From a new viewpoint, the chart has been redefined as chart set. And characters of chart differing from terrain map and the specific quality assessment indexes have been discussed. Some innovative ideas of the research work were as follows: 1) Establishing a new tetrahedron model of quality control. The relationship between error and quality assessment was analyzed and practicability was adopted to assess the quality of chart product. 2) Defining the chart set. After changing from paper chart to electronic chart or digital chart, chart product become a set of digitizing collecting, storing and renewing data. 3) Building up the user assessment system of the chart product, which would perform real-time chart quality control
