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。
The Traditional analog photogrammetric plotting and analytical mapping is not able to satisfy the need of basic spatial information production yet. 傳統的模擬測圖系統和解析測圖系統，已經(jīng)無(wú)法滿(mǎn)足基礎地理空間信息生產(chǎn)的要求。
