基于ArcGIS的输气管道分布式测绘数据库

Establishment of Distributed Surveying and Mapping Database for Gas Pipelines Based on Arcgis

随着全国天然气管道项目的迅速发展,相关的测绘数据量也随之迅速增大,同时地理信息系统和计算机数据库管理技术也日趋成熟,如何运用这些先进技术来管理数据成为当前亟待解决的问题。在ArcGIS的基础上,分析现有的输气管道相关测绘数据结构,提出利用空间数据引擎ArcSDE对输气管道相关测绘数据进行管理,根据对分布式测绘数据库的体系结构设计、数据组织、数据入库方式等方面的阐述,提出了一种建立和管理输气管道分布式测绘数据库的方法。按照此方法建立输气管道分布式测绘数据库后,再结合具体业务优化系统功能模块,最后建立更科学的输气管道数字化业务平台。

With rapid development of gas pipeline construction in China,relative surveying and mapping data quantity have been increased rapidly and geographic information systems and computer database management technologies are also becoming mature gradually.How to apply such advanced technologies in relative management has become one of the most pressing issues at present.Analyzed are structures of available surveying and mapping data relative to pipeline systems and proposed is the idea that ArcSDE,the spatial database engine,is used to manage such surveying and mapping data.Described are structural design,data organization and data storage method of distributed surveying and mapping database system and put forward is a method for establishing and managing such database.Distributed surveying and mapping database can be established for gas pipeline according to this method,system function modules can be optimized in combination of specific operation and a more scientific pipeline digital business platform can be established accordingly.
