摘要
在测绘生产中,我们常用的GIS软件不能直接使用源数据,需要进行数据预处理及数据准备。矢量数据符号化是地图可视化的关键步骤,是在进行数据预处理及数据准备时工作量大、耗费时间长的一项工作。本文从实际测绘生产任务出发,设计了地图数据符号化方案,开发了相应的符号化软件,极大地提高了生产效率。
In surveying and mapping production, people cannot use source data directly in the commonly used GIS software, which needs data pre - processing and data preparation. Vector data symbolization is the key step of map visualization that consumes large a- mount of time and human resources in data preprocessing. In the light of surveying and mapping production practice, the authors de- signs the plan of map data symbolization, develops corresponding symbolization software, and greatly improves production efficiency.
