摘要: 在研究中国《地球空间数据交换格式》标准的矢量数据交换格式的基础上,提出了矢量空间数据的两种属性分类概念,并就标准的功能扩充作了简要的论述和建议。Abstract: CNSDTF is a national commend standard for the transformation of geo-spatial vector data. There are some difficulties when transferring digital map with this CNSDTF. This paper expounds a new concept that there are two kinds of attribute classes in geo-spatial vector data after researching this standard earnestly, and discuss the extension of functions for CNSDTF briefly.
