摘要: 随着城市信息化建设特别是GIS应用的发展, 对大比例尺数字图的需求日益增加.以往的测图软件往往着重于制图的需要, 很少考虑GIS应用的需求.在MAPGIS平台的基础上, 根据系统性、兼容性、扩展性和开发性等原则, 详细探讨了大比例尺数字测图系统的整体结构、数据组织、工作流程, 设计了一个完整的数字测图系统.该系统具有野外数据采集、输入、处理、联接成图、编辑与修改及绘图等功能, 在输入地物图形的同时, 可以输入图形属性信息, 输出符合国家标准图式的图形, 并自动生成和维护拓扑关系.输出成果数据可以直接进入GIS系统, 进行分析处理Abstract: With the development of city information building, a large scale digital surveying and mapping system is widely used in urban geographic information system. In the past, some digital surveying and mapping systems emphasized mapping, and hardly considered application of GIS. This paper discusses the general structure, data organization and function of the system. It also introduces data input, data process and output of many kinds of maps. According to system solutions, compatibility, expansibility and opening fundamental, a whole digital surveying and mapping system is designed and developed based on MAPGIS. The system can perform data collection outdoors and making map automatically indoors. In other words, the system has the functions about data loading, collecting, reading, analyzing, dealing with, mapping, editing, changing and printing etc. At the same time, the system can input the attribute information of surveying object, make maps with topology relation, and print maps that meet the national standards.
