选择性压盖技术在纸质海图生产中的应用

利用数字海图数据直接出版纸质海图是提高纸制图生产效率的重要手段，但由于数字海图与纸质海图在编制原则和表现规范上的差异造成由数字图生产纸质图时，需要大量的手工修编，从而增加了工作量，延长了成图周期。采用一种新的制图理念，利用ArcInfo的选择性压盖技术，制作纸质图符号库，选择正确符号化顺序，从而实现纸质海图生产与数字海图生产同步，减少重复劳动，缩短成图周期，提高了工作效率。

The Application of Selective Mask Technique to the Production of Paper Chart

Using digital chart to produce paper chart directly is an important way of high-cycle efficiency.But the difference between digital chart and paper chart lead to repetitive work.Based on Arc/Info selective mask technique and rebuilding the chart symbol,the authors design a new way to produce paper chart.The new technique can avoid repetitive work and overlong cycle.
