After transformation of the data model and processing of the thematic mapping elements, the paper constructs a mapping system of the seabed sediment thematic digital map. 經(jīng)過(guò)對數據模型的轉換以及專(zhuān)題制圖要素的處理，建立了海洋底質(zhì)專(zhuān)題數字圖成圖系統。
Along with the application of digital cartography in the field of Cartography, developing the system for digital mapping becomes inevitable. 隨著(zhù)數字地圖制圖技術(shù)的逐步成熟，有必要研制開(kāi)發(fā)適合多比例尺數字矢量地形圖生產(chǎn)的數字測圖系統。
