【摘要】:目前Auto CAD制圖數(shù)據(jù)與Arc GIS地理數(shù)據(jù)在格式轉換上普遍存在著信息丟失、效率低下、用戶自定義的地物無法轉換、屬性數(shù)據(jù)不能自動轉換等問題,對兩種圖形文件的空間數(shù)據(jù)模型結構進行了研究,分析它們空間圖元結構與關系,研究轉換中涉及的關鍵技術并提出具體轉換模型。在理論研究的基礎上采用.net框架C#面向對象技術編寫轉換程序,實行了兩種數(shù)據(jù)的無損轉換,為其他類型的數(shù)據(jù)轉換提供了有益參考。
[Abstract]:At present, there are many problems in format conversion between Auto CAD cartographic data and Arc GIS geographic data, such as information loss, low efficiency, user defined features can not be converted, attribute data can not be automatically converted, and so on. In this paper, the spatial data model structure of two kinds of graphic files is studied, the structure and relation of their spatial graph elements are analyzed, the key technologies involved in the transformation are studied, and the concrete transformation model is put forward. On the basis of theoretical research, the conversion program is written by using .net framework C # object-oriented technology, and the lossless conversion of two kinds of data is implemented, which provides a useful reference for other types of data conversion.
