MAPSUV中高程数据变换的方法与应用

Method and Application of Elevation Data Conversion in MAPSUV

通过分析MAPSUV系统中高程注记和高程变换的特点及对MAPGIS明码文件的研究,提出了利用MAPGIS明码文件变换高程注记的方法。此方法方便快捷,并能在保持原注记位置不变的基础上修改高程值,比其他高程变换方法效果好、更加实用。

By analyzing the elevation note and elevation transform characteristics of MAPSUV system and studying the ASCⅡ of MAPGIS system, this paper proposes an elevation note transform method by using the ASC Ⅱ of MAPGIS system. This method is convenient, fast, and able to amend the elevation value on the basis of maintaining the same position of note, better than other elevation transform methods, so more practical.
