摘要:
矢量数据符号化是GIS中空间信息可视化的一种主要方法,通常是采用完全基于矢量技术的算法实现.作者通过对栅格数据和矢量数据各自优缺点的分析、比较及应用研究,提出一种基于矢量栅格技术的矢量数据符号化方法,在符号库法符号化的软件系统中采用这种方法,可以消除矢量技术产生的不良图形,降低算法的复杂程度,减少计算机的时间开销,提高符号化的整体速度.
Abstract:
Vector data symbolization is a main method of GIS spatial information visualization. It is usually realized based on vector technique. After analysis and comparison to raster data and vector data, this paper provides a new method for vector data symbolization. It is based on vector and raster data. The research shows that the technique used in data symbolization improves the unreasonable graphics, reduces the complexity of the algorithm and time spent.
