基于空间数据格式的多异性和兼容性较差的特点,以及地理空间数据互操作的要求,分析了空间数据的多尺度的特征,提出基于可缩放矢量图(SVG)文件格式组织空间数据,对不同分辨率的空间数据采取分级表达,并描述不同尺度空间数据的关联关系.

Due to the difference between file formats and bad compatibility,and the demands of the inter-operation of spatial data, this paper analyses multi-scale characteristics of spatial data.It shows the method of organizing the data based on SVG technology,and represents different scale spatial data with different grade,and describes the relat...
