In order to ensure the accuracy of road network analysis and to establish network set, it is necessary to make topological errors on road layers to ensure the connectivity of road networks. The concrete operation flow is: Road topological error-establishing geometric network set-road network Service release.
1. Road topology Error:
(1) Creating a personal geodatabase and feature set through Arccatalog,
(2) In the feature set right-click menu, import the corridor layer,
(3) New-Topology, Popup interface in the right-click menu of the feature set:
(4) Finally drag and drop the topology road layer into ArcMap for topological errors, using the ArcGIS Topology tool to eliminate line errors.
2. Set up a geometric network:
(1) Create new-network dataset in the right-click menu of the feature set, popup interface:
3. Network Service Release:
① Create an ArcMap document, the data source in ArcMap is obtained from the above established network set and the road layer after the topological error, as follows:
Based on the ② map service, tick the network analysis option.
③ after entering the URL of the network service, it appears as follows:
