数字制图在地质制图中的应用

THE APPLICATION OF NUMERICAL CARTOGRAPHY IN THE GEOLOGICAL DRAWING

数字制图技术经过多年的开发和应用，取得突破性进展，已实现了彩色地学图件从输入、编辑、打样到生成制版胶片的全过程的电算化，可用于生产符合公开出版质量的图件。与传统手工方式比较，数字制图具有减少工序，缩短地图修编周期，实现了地图数字化，可最大程度的实现信息共享的优越性。从数字制图工艺及生产流程等方面阐述了数字制图在地质制图中的应用。

The technique of numerical cartography,as a result of development and the application of many years, has obtained the breakthrough develoment, and has realized using computer to echieve the full course of input, editor, sampling and film making, Its production can fits openly publishing quality.Comparied with traditional handwork method,the numerical cartography not only decreases process,but also shortens the map repairs compiling Period,and has realized the map figureization,Therefore it has the superiority of realization information to be shared at the biggest level.The author expound the application of numerical cartography in the geological drwwing from the technics of numerical cartography to the process of production.
