In the process of urban drainage network census,topological analysis of the generated geographic database vector data is related to the integrity and rationality of the final drainage network information.In the whole urban drainage pipe network system,all outlets are distributed in specific places such as rivers and sewage treatment plants,but errors in node coordinate entry and topology in the drainage pipe network will generate"wrong outlets"in the drainage official website database.This paper expands the function of geometric network analysis in ArcPy,the third party database of ArcGIS,to quickly find and generate the"wrong outlet"in the database of urban drainage pipe network.
