| Abstract: | To realise the product in traditional reference coordinate system with the product in CGCS2000,the author studed the transformation in digital terrain map from BJ54 to CGCS2000.The method and diagram of transformation of digital terrain map is described in this paper,and the transformation method of all kinds of corresponding ObjectARX class in digital terrain map are analyzed detailedly,achieved that in the AutoCAD environment,transformed successfully the topographic map from traditional reference coordinate system to CGCS2000 conversion. |
