摘要
随着计算机、网络等高新技术的飞速发展和广泛应用,地图出版逐步由传统的模拟阶段发展到数字阶段。文中分析了当前数字地图出版中数据输入尤其在矢量数据输入方面存在的诸多问题,指出了多源矢量数据利用的重要性。对数字地图出版中多源矢量数据利用理论进行了探讨和研究,提出了源数据描述、数据结构映射和数据重组的解决方案。最后通过MapGIS明码格式数据进行了实现。
With the rapid development and the wide application of high-tech such as computer technology and internet, map publish is developing from traditional analogue phase to digital phase. This paper analyzes the problems in data input of digital map publish especially in vector data input, and indicates the importance of multi-source vector data use. It also discusses the theory about it, and puts forward three steps such as source data description, data structure mapping and data recombination. An example about MapGIS ASCⅡ format data is provided in the end.
