摘要
本项目系统利用FME先进的数据语义转换模型,结合MicroStation对DGN格式地形图的先天处理优势,再将计算几何原理应用到空间数据处理中的复杂算法运算,对现有的1∶500地形数据进行自动综合缩编,提高了地形图缩编工作的自动化程度,提高了工作效率。
The project system uses the advanced FME data semantic conversion model,combined with the innate advantage of Microstation DGN format topographic maps, and then applies the principles of computational geometry to complex algorithms in spatial data processing operations, downsizing of the automatic integrated in the existing 1 ： 500 terrain data, raise the level of automation of a drawdown of topographic maps, greatly improve work efficiency.
