城市供水管线数据采集及数字化成图研究

Research on data acquisition and digitized graph of urban water supply pipeline

提出了全新的管线数据外业采集作业模式,设计了管线点、线表的数据结构,并基于MAPGIS二次开发的供水管线平台进行数字化成图,论证了其可行性和先进性,通过南京市江北片区城市供水管线普查项目的实践分析,表明整个作业流程和方法有较强的推广应用价值。

The new work pattern of field survey data acquisition was put forward, and designed the data structure of pipeline point paper and line paper, established the pipeline database. Innovative used water supply pipeline platform based on the secondary development of MAPGIS for the digitized graph, and demonstrated the feasibility and advancement. By the practice analysis of Nanjing Jiangbei regional urban water supply pipeline survey program, great popularization using value of the whole work flow and method was showed.
