Update Node Weight

Temporarily updating the weights on the nodes when the network turns in the memory adjacency list.

When using the Update Node Weight function, you need to pay attention to the following issues:

Set Turn Table before using the Update Node Weight feature. Otherwise, the Update Node Weight function cannot be applied. For the use of the steering table, see Steering table .
After a node is set as an obstacle point, its weight is -1.
When there are multiple arcs adjacent to a node, multiple turning directions will be generated. The turning direction can be determined according to the start ID and end ID of the arc, and the weight value can be set for each turning direction.

Network Dataset opened in the current Map.
Set information such as Network Analysis Weight Field and node/Edge ID Field in the Network AnalysisEnvironment Settings window. For an introduction to the Network AnalysisEnvironment Settings window, see the Network AnalysisEn vironment Settings window page.
In the toolbar of the Environment Settings window, click the Weight Settings Drop-down Button and select the Update Node Weight "item to display the Update Node Weight" dialog box.
Click to select the node whose weight needs to be updated in the network layer, and the information of the selected node will be automatically added to the list in the dialog box. You can select the row where the node is located, and click the node cell to modify the direction, weight, and whether it is an obstacle point of the node. For the updated node, the arc segment of the currently selected steering direction is highlighted. The point is highlighted in red when set as an obstacle point.
Continue to update the weights of other nodes.
Continue to set Backwoard Value and Prohibited Value.
After setting, click the "Apply" button to save the modifications; click the "Close" button to abandon the modifications and exit the current dialog box.
