Connectivity between Two Points
Instructions for use
Analyze whether the two points are connected according to the specified start and End Node. Can be used to determine the connectivity of two specified points in an underground pipe or road.
Operation steps
- Opens the network layer in the current Map.
- Before proceeding with Network Analysis, you need to set up the Network Analysis environment. On the Spatial Analysis tab, in the Facility Network Analysis group, select the Environment Settings "check box to display the Environment Settings" Dock Bars. In this window, set the weight field, node/Edge ID Field, Enable Rules, and steering table of Network Analysis. For an introduction to the Environment Settings window, see Network AnalysisEn vironment Settings window Page.
- On the Spatial Analysis tab, in the Facility Network Analysis group, click the Network Analysis Drop-down Button. Select Two-point Connectivity from the drop-down menu to create an instance of Connectivity between Two Points. For an introduction to instance windows, see Introduction to Instance Management window Pages.
- In the current network layer, click to select a Start Node to add. There are two ways to add an event point. One is to click the mouse on the Network Data layer to complete the addition of the Start Node; One is to import the point object in the Point Dataset as a Start Node. For details, see the Import Stops dialog box. A Start Node for
Connectivity between Two Points can only be added once. Once added, the point is automatically added to the Start Node information directory tree in the Instance Management window.
- The addition method of End Node and obstacle point is consistent with that of Start Node. End Node and obstacle point can be added by referring to the addition method of Start Node.
- After you add a Start Node, End Node, or obstruction point, Click the Execute button in the Facility Network Analysis group on the Spatial Analysis tab or click the Execute button on the Instance Management "window. The Connectivity between Two Points operation is performed.
- After The execution completed, the Output Window will prompt Analyst Result: "Two points connected" or "Two points disconnected".
Precautions
- For the node information added to the event point directory tree, you can Export as Point dataset to facilitate the use of similar Network Analysis.
- The event points of the Connectivity between Two Points may be on network arcs and network nodes or nearby areas within the capture tolerance.
- When the location of the event point needs to be changed, you can click the Move Stop by Mouse "button in the toolbar of the Instance Management" window, select the event point with the mouse, and drag it to the appropriate location.
