Urban Drainage Pipeline Network GIS Data Validation Technology and Software Development
摘要
Abstract
Geo-information system(GIS)is a frequently-used database in the construction of"smart water"systems.Due to errors in the establishment and maintenance of databases,various anomalies exist in the actual drainage pipe network GIS,affecting the accuracy and effectiveness of drainage pipe network operation analysis,simulation,and management decisions.Therefore,it is necessary to study validation technology for drainage pipe networks GIS to ensure the quality of GIS data.This study proposed topological information construction algorithms,and summarized common anomaly forms such as topology,text attributes and numerical attributes.Based on these,general validation methods for each type of data were proposed.A software platform integrating drainage pipe network GIS topology and attribute validation technologies and capable of outputting validation result reports,was developed and applied to validate the sewage pipe network GIS of Z City.The results showed that there were 24 336 abnormal records in the city's drainage pipe network GIS,and more than 67％of the anomalies had been improved during validation,indicating that these validation technologies can effectively detect and repair various GIS anomalies.关键词
