GIS数据处理技术的应用

Based on the GIS Data Acquisition and Processing Technology Research

北京市基础测绘是一项重要的工作,为加快基础测绘地理信息数据的生产和建库,研制出了大比例尺1:500地形图数据加工工艺流程。介绍了北京市测绘设计研究院设计的一种数据模型的数字化生产过程,使生产的DWG数据图形的可视化显示与图形的属性数据有机的结合在一起,能直接派生满足制图需求的模拟图,又能派生GIS数据。

Basic Surveying in Beijing is an important work. In order to speed up the basic surveying and mapping geograph- ic information data production and database, we developed a large-scale 1 ： 500 topographic data processing work flow . This paper introduces the digital production processing based ona datamodel in Beijing Institute of Surveying and Mapping. This processing combined organically the DWG data graphic visualization and attribute data, and could produce the simulation map which meets the mapping needs and GIS data.
