针对现有的矢量数据渐进传输校验空间对象拓扑数量大，提出一种改进的矢量数据渐进传输。根据定义的算法删除有效性最低的点，并检测生成的空间拓扑是否自相交，优化需要检验的拓扑图形的数量。通过设计的一个在客户端服务器架构基础上的原型，采用真实数据集进行测试。实验结果表明，传输矢量生成算法保持空间对象的拓扑和防止不同图层的自相交，降低了客户端的响应时间。

For the large number of objects topology in parity space of progressive transmission of vector data,we propose an improved progressive transmission of vector data,it removes the lowest effective point according to the defined algorithm,and detects whether the generated spatial topology is self-intersection or not,this optimises the number of topology graphics to be verified.Through a designed prototype based on client-server architecture,we use real data sets to test.Experimental results show that the transmission vector generation algorithm maintains the topology of space objects and prevents different layers from self-intersection,these reduces the response time at client end.
