自定义形文件在入库和数据转换时多无法识别和显示，但形文件的定义一般遵循国家标准，数据多通过几何属性或扩展属性进行属性信息记录。因此本文结合工作实际，分析数据的属性信息组织特点，提出以地物编码结合地物几何属性信息方法，实现了自定义符号库的多元数据转换问题。通过两种信息的结合，最大化的保留转换前的信息，实现了几何图形与地物属性的一体化转换，为数据无损转换及入库提供一种新的转换思路。

User-defined Shape Files cannot be properly appeared and recognized during data transform ,but these files are always defined by national standard ,which are realized by proper usage of Geometry information or extended informa -tion.Together with practice ,by analyzing the arrangement characters of different information ,a new method was put up in this paper which helps data managers to realize data transformation by element code and geometry information .The best ad-vantage of this method is to keep the consistence of former data ,which means a new way for spatial dada management .
