When performing network analysis, you need to first specify network locations involved in the analysis. For example, route analysis requires specifying stops, while finding the nearest facility requires defining facility points and event points. There are two methods to add sites: one is clicking directly on the network data layer to add sites; the other is importing point objects from point datasets as sites.

Add by Mouse

Click the "Add by Mouse" button on the toolbar in the instance manager window. The cursor will change to an add-state in the map. Left-click at appropriate positions to add sites. Each added site will automatically appear in the stop info of the instance manager window. Right-click to finish the operation. Note: Ensure proper node tolerance setting. If clicking position exceeds node tolerance, site addition may fail.

Import Stops

Import point datasets from current workspace as sites. Right-click the "Stops" node in the instance manager window's tree directory, select "Import" from the context menu to open the "Import Stops" dialog. Barrier point import follows similar procedures.

Parameter Description：

• Source Dataset

  Datasources：Select the datasource containing point data.

  Dataset：Select the point dataset to import.

• Name Field：Select a name field. After successful import, site names will display corresponding attribute values from this field.
• Node Filter

  Set conditions for imported points. Only points meeting criteria can be imported as stops, facilities, events, centers or barriers. You can either directly input expressions or click the button to build filtering expressions in the "SQL Expression" dialog. For SQL expression construction, see SQL Expression Query.

• Clear Existing Stops：When checked, existing stops will be deleted before import. The result retains only points from current dataset or those meeting filter conditions.
