Method and system for updating and warehousing urban pipelines on basis of ArcGIS (geographic information system)

Abstract

The invention discloses a method and a system for updating and warehousing urban pipelines on the basis of an ArcGIS (geographic information system). The method includes the following steps of acquiring spatial ranges of data of source databases; deleting certain data in target databases; establishing attribute import configuration; importing the data in the source databases into the target databases according to the attribute import configuration and cleaning and filtering certain attribute data; performing edge matching, and specifically, manually correcting and adjusting urban pipeline data and pipe point data in conflict ranges; establishing attribute association relationships among the urban pipelines and pipe points according to geometric network interfaces, namely assigning values to pipeline and pipe point association attributes in urban pipeline spatial databases by the aid of geometric network development interfaces; establishing the attribute association relationships among the urban pipelines and the pipe points; and updating and warehousing the data. The certain data which are deleted from the target databases correspond to the acquired spatial ranges. The certain attribute data do not conform to database constraints in the target databases. The method and the system have the advantages that urban pipeline updating and warehousing processes can be standardized and unified by the aid of the method and the system, and the method and the system provide a powerful support for application such as data sharing, migration and integration for the urban pipelines.

Description

technical field [0001] The invention relates to a method and system for updating and storing urban pipeline data based on ArcGIS. Background technique [0002] As a national strategic municipal facility resource, urban pipelines have received more and more attention. The State Council and relevant government units have repeatedly emphasized the need to load the construction of urban infrastructure resources. Although great achievements have been made in the system construction of urban pipelines and the formulation of standards and specifications, there are still great barriers in the integration and sharing of urban pipelines, and there is a serious lack of updating methods and systems for urban pipelines based on ArcGIS , resulting in serious islands of data and information, and there are great obstacles to the maintenance and construction of urban pipeline facilities. [0003] Analyze the characteristics of urban pipeline data, mainly in the following aspects: [0004]...

AI Technical Summary

Problems solved by technology

Obviously, it is impossible to judge whether it belongs to the newly added data set, deleted data set, modified data set, or unchanged data set only by the time and unique number.

[0024] 4. The key problem is that when the urban pipeline is updated, it is impossible to guarantee that the unique code of the updated pipeline data and the unique code in the official database are not repeated, let alone guarantee the relationship between the pipeline and the pipeline

If the relationship between pipelines and pipe points of urban pipeline facilities cannot be guaranteed, there will be no better seamless migration, integration and sharing
