When conducting Network Analysis, it is necessary to first specify the network location involved in the analysis. For example, when conducting path analysis, it is necessary to specify the site, and when finding the nearest facility point, it is necessary to specify the facility point and event point. There are two ways to Add Site, one is to click the mouse in the Network Data layer to complete the addition of the site; the other is to import the point object of the Point Dataset as the site.

Add by Mouse Site

Click Add by Mouse "in the toolbar of the Instance Management window. The mouse in the Map will change to Add status. Click Add site at an appropriate position in the Map. Each time a site is added, the point is automatically added to the Stop Info in the Instance Management window. When you are done, right-click to end the operation. Note: The appropriate Node Tolerance needs to be set. If the mouse click position exceeds the Node Tolerance, the site addition may fail.

Import Stops

Import a Point Dataset from a Current Works pace as a site. Right click the Site directory node in the tree directory of the Instance Management "window, and select the Import command in the pop-up Context Menu. The Import Stops" dialog box will pop up. Obstruction points are imported in a similar manner.

Parameter Description:

• Source Data

  Datasource: Select the Datasource where the point data is located.

  Dataset: Select the Point Dataset to import.

• Name Field: Select a name field where Site Name will be displayed as an attribute after a successful import.
• Node Filter Certain conditions are set

  for the imported points, and only the points meeting the conditions can be imported as stations, facility points, event points, center points, obstacle points, etc. When using, you can either enter the expression directly, or click the button on the right to build the expression for filtering in the pop-up "SQL Expression" dialog box. See the SQL Statement Query for how to build the SQL expression.

• Clear Existing Stops: Select this check box. When importing Stops, the added site will be deleted, and then the Stops will be imported. The result of the import is to keep only the points in the Current Data set or the points that satisfy the Filter.
