给排水管网数据从AutoCAD至ArcGIS转换的研究

摘要

通过探讨给排水管网图形数据和属性数据从CAD到ArcGIS的转化过程,提出了逻辑组织、图形转化和属性设计等方面的一些实用的解决方案;并结合Geodatabase地理空间数据库建立的整个过程,分析了在图形转化、数据录入等方面的注意事项.这些方法在"奥运中心区雨水排除系统研究"等多个项目中应用,均取得了理想效果.%By discussing the conversion process of the graphics and attribute data of water and wastewater pipe network from CAD data format to ArcGIS format, some practical solutions, such as logistic organization, graphic conversion, and attribution design were put forward. Based on the building process of Geodatabase, the attentions about graphic conversion and data collection should be analyzed. These methods were applied in many projects including "Study on the storm water system in the Olympic Green", and all these projects were successful.
