快速制图服务系统在三调成果图集编制中的应用

Application of rapid mapping service system in the compilation of atlas of the three modulation results

三调成果数据中各图斑数据仅有类型信息而没有属性信息,仅根据该成果数据无法成图。传统的制图工艺较为烦琐,耗时相对较长。快速制图服务系统最大限度地利用计算机技术,能快速完成不同比例尺专题图的制作和输出。文章提出一种基于快速制图服务系统的三调成果图集编制方法,对三调成果数据进行分析、处理,同时通过江苏省快速制图服务系统从快速制图数据库中提取相应的地理要素,在快速成图子系统中进行叠加和镶嵌等处理,形成三调各个调查单元的成果图。该方法在提高制图效率的同时保证制图表达的科学性和准确性,为当前的地图制图工作提供参考。

In the result data of the third land survey each map spot data only has type information but no attribute information,so it cannot be mapped only based on the result data.The traditional drawing process is more complicated and time-consuming.The rapid mapping service system makes the best use of computer technology and can quickly complete the production and output of different scale thematic maps.In this paper,a compilation method of the result atlas of the third land survey is proposed based on the rapid mapping service system,which analyzes and processes the result data of the third land survey.At the same time,the corresponding geographical elements are extracted from the rapid mapping database through the rapid mapping service system of Jiangsu province,and the result map of each investigation unit of the third land survey is formed by superposition and mosaic processing in the rapid mapping subsystem.This method can not only improve the efficiency of cartography but also ensure the scientificity and accuracy of cartography expression,so as to provide reference for current cartography work.
