一种改进的矢量数据渐进传输
AN IMPROVED PROGRESSIVE TRANSMISSION OF VECTOR DATA
摘要
Abstract
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.关键词
