Topographical maps are the principal frame form of gis, and realization map digitizing and offering gis basic spatial data is one of the important research fields in surveying and gis, which is also necessity of development of science and technology. based on building gis - oriented topographical mapping system theories, this themes apply the advanced objectarx technology, aim at topographical mapping and exporting to gis, and resolve several key problems, such as symbols analysis and building, dtm and contour line automatic drawing, topographical map adjoining, digital image rectifying etc. and it offers models and arithmetic, realizing the general functions of gis - oriented topographical mapping system
本文以建設面向gis的測量繪圖平臺理論為基礎，以autocad平臺下objectarx開發技術為核心，圍繞地形圖的成圖和入庫（ gis數據庫）這一課題，對其中的關鍵技術難題? ?符號庫的建立與實現、 dtm與等高線的自動繪制、地形圖接邊、數字化柵格圖像的定向與糾正、介面數據文件的生成等進行了研究分析，提出了相應的模型和演算法，實現了面向gis的測量繪圖系統的基本功能。
