随着地图制图学的发展和GIS应用范围的扩大,以及人们对矢量化地图的需求的增加,基于GIS技术的地图数字化尤其是扫描矢量化方法已经成为现代数字制图技术的主要方法之一。 With the development of cartographic and GIS application of the expansion, and the people of vector maps of the increased demand, based on GIS technology of digital maps in particular vector scanning method has become the modern digital mapping technology one of the main methods. 因此,如何提高矢量化地图的数据质量也已成为人们日益关注的问题。 Therefore, how to improve the vector map data quality has become a growing concern.
本文以制作《郑州市城区图》为例,通过描述地图矢量化的步骤,分析扫描矢量化方法的技术要点,对地图扫描矢量化过程中产生的固有误差、人为误差等进行分析,并利用所学的结点平差、拓扑校正等数据质量控制方法对扫描矢量化地图的数据进行质量控制。 In this paper, for the production of "Zhengzhou City map" for example, described by vector map of the steps, methods of vector analysis scanning the technical points of the vector map in the process of scanning the inherent error, human error, such as for analysis and use of Adjustment of the node, topology correction of data quality control methods such as scanning vector maps of the data quality control.
