针对数字环境下的纸质海图生产,本文提出一种顾及海图实体规则和海图要素制图规范的海图要素质量检测方法,将海图要素按照其变化速度的特征,分为变化缓慢,变化频繁但有规律可循或有据可查和变化频繁且无规律可循几个类型,同时考虑要素本身规则和要素相互间的关系,探讨建立质量检测规则库的方法,为在数字环境下出版的纸质海图的质量检测和控制进行了有益的探索。
針對數字環境下的紙質海圖生產,本文提齣一種顧及海圖實體規則和海圖要素製圖規範的海圖要素質量檢測方法,將海圖要素按照其變化速度的特徵,分為變化緩慢,變化頻繁但有規律可循或有據可查和變化頻繁且無規律可循幾箇類型,同時攷慮要素本身規則和要素相互間的關繫,探討建立質量檢測規則庫的方法,為在數字環境下齣版的紙質海圖的質量檢測和控製進行瞭有益的探索。

Aiming at the production of paper charts in digital environment ,a new quality inspection method based on cartographic specifications and entity rules is put forward in this paper .maritime features are classified into three catego-ries according to their changing features:low changing speed , fast changing speed with regulations , fast changing speed without regulations .At the same time ,rules of each feature and its relationships with some other features are analyzed ,to discuss how to establish quality inspection rule base ,paper chart ’ s quality inspection and control has carried on the ben-eficial exploration .
