Digitising Network Objects
New network objects can be created on the GeoPlan, the Long Section window or on the appropriate grid view.
There are several features that can be used to speed up the digitisation process:
- Automatic Node Naming is used to name each node as it is created. The node name can be based on node location or a user specified custom pattern. See Automatic Node Name Generation for details.
- Digitisation templates can be used to set default values for object parameters. The default values are applied to the objects when they are created. This allows similar objects to be created quickly without having to set data values for each individually. See Setting Default Values for details.
- Disabling the Name Dialog prevents the object name dialog appearing each time an object is created. This option is set on the General Page of the GeoPlan Properties dialog.
- Disabling the Property Sheet prevents the property sheet appearing each time an object is created. This option is set on the General Page of the GeoPlan Properties dialog.
To create a network object on the GeoPlan:
- Select the type of object to be created from the New Object Type dropdown list on the GeoPlan Tools toolbar.
- Click New Object () to turn on New Object mode.
- Click on the location of the object in the GeoPlan to digitise the object. Details on how to edit the different object types are given below.
- When the object has been digitised a Create New Object dialog is displayed. Enter the required data in the dialog and click OK to create the object.
Using the New Object tool click on the location where the new object is to be added.
To insert node into an existing link:
- Click on the link on the GeoPlan Window while in New Object mode. The Create New Node dialog will be displayed.
- Select the Split option to split the current link and create two new links connected to the new node.
- Set a flag to apply to calculated fields if required. The flag will be applied to the following pipe fields:
- US/DS Node ID (Collection Networks), Start/End Node ID (Distribution Networks)at location of inserted node.
- Pipe Length (if the length field of the original pipe is not set to #D).
- US/DS Invert Level at location of inserted node (Collection Networks only).
- For Collection Networks, the option to Automatically Split CCTV Surveys is available. Select this option to split CCTV Surveys associated with the pipe to be split. InfoAsset Manager will:
- Split the survey to create two new surveys. Each newly created survey will be given an ID based on the original survey from which it was created. Information from the original survey will be copied to created surveys.
- A 'Remarks' defect code will be created at the point at which the original CCTV Survey is split. i.e. at the start of one of the newly created surveys and at the end of the other.
- The Surveyed Length, and defect Distance fields of new surveys will be updated to apply to the pipe the survey is associated with. The Upstream Node ID and Downstream Node ID of new surveys will correspond with the pipe the survey is associated with.
- The Split Survey Reference of each new survey will be populated with the ID of the survey from which it was created.
- The original CCTV survey will be updated so that the Split Survey field is checked. (When validating the network, validation rule 401 - CCTV Survey is not associated with a pipe in the network - will not be applied to any survey with the Split Survey field checked.)
To add a lateral connection to an existing pipe / link:
- Click on an existing pipe / link on the GeoPlan in the position where you want the new lateral connection. The Create New Node dialog is displayed.
- Enter a unique node name and select the appropriate type.
- Check the Add Lateral Node box. The pipe / link with which the new node is associated is shown in the Pipe list. You can change the pipe / link on this list if necessary.
Using the New Object tool, click on the location where the new object is to be added.
- Click the node at the upstream end of the new link. The cursor is now attached to the upstream node by a red line. If there is more than one node beneath the cursor, a dialog is displayed allowing the upstream node to be selected.
- Click one or more intermediate points to digitise bends.
- Click the downstream node to complete the link.
It is possible to add links without connecting both ends to nodes or connection nodes. This allows assets or ancillary structures to be placed without worrying about connectivity.
See the Reserved Node Names topic for information on node names used as upstream and downstream node IDs for unconnected pipes.
To create an unconnected link using the New Object tool:
- Click the start point of the new link. The cursor is now attached to that point by a red line.
- Click one or more intermediate points to digitise bends.
- Double click on the end point of the new link to complete the link. The Create New Pipe dialog is displayed. The names of the upstream and/or downstream nodes are set to Unknown. Multiple unconnected pipes will be differentiated by the Suffix.
If close to an existing node, InfoAsset Manager will attempt to snap the start point of the pipe to the node. To prevent this from happening, switch snapping mode off.
Single links can be created as described above. There is a method that allows nodes and pipes to be created together, to create a run of nodes and pipes quickly.
To add a run of nodes and links using the New Object tool:
- Select a link type to be created from the New Object Type dropdown list.
- Hold down the Ctrl key and click to add the upstream node. This displays the Create New Node dialog.
- Click on intermediate points to create link bends.
- Hold down the Ctrl key again and click to add the new downstream node. This displays the Create New Node dialog again.
Surveys can be created as scheduled tasks.
To create a survey using the New Object tool:
- Select Survey/ Repair Task on the New Object Type dropdown list on the GeoPlan Tools Toolbar.
- Click New Object () to turn on New Object mode.
- Click on the location of the survey in the GeoPlan to digitise it:
- Acoustic Survey (Collection Networks only) - click on the pipe for which the survey is to be created.
- CCTV Survey (Collection Networks only) - click on the pipe for which the survey is to be created.

- General Survey Line - click on the link or line for which the survey is to be created (excluding Collection Network pipe objects).
- Water Quality Survey - click on the asset for which the survey is to be created (excluding Collection Network pipe objects)
- User Defined Survey - click on the GeoPlan location where the new object is to be added.
- The Create Scheduled Tasks dialog is displayed.
- Select the type of survey to be created and set the creation options as required.
- Click OK to create the task.
All surveys can be created by clicking anywhere on the GeoPlan. However, line based geometry tasks such as CCTV surveys will not have any geometry and will not be associated with an asset. This will have to be done manually in the survey property sheet.
Each survey type can also be created via the Scheduling | Create scheduled tasks option from the Network menu or the button of the Scheduling Tools Toolbar. Both alternatives also lead to the display of the Create Scheduled Tasks dialog.
Digitisation rules when creating the survey may differ between surveys.
Finally, surveys can also entered manually in the corresponding tab of the Survey Grid. Refer to the Creating Objects on the Network Grid Window section for more information.
Smoke Defect Observations (Collection Networks only) have got a dedicated button ( ) for their creation on the More GeoPlan Tools toolbar. Please refer to the Smoke Defect Observations topic for further information.
All repairs can be created individually as scheduled tasks.
To create a repair using the New Object tool:
- Select Survey/ Repair Task on the New Object Type dropdown list on the GeoPlan Tools Toolbar
- Click New Object () to turn on New Object mode.
- Click on the location of the repair in the GeoPlan to digitise it:
- Pipe Repair- click on the pipe for which the repair is to be created.
- Manhole Repair - click anywhere on the GeoPlan or the node for which the repair is to be created.
- Pipe Clean - click on the pipe for which the repair is to be created.
- General Maintenance - click anywhere on the GeoPlan or on an object for which the maintenance is to be created.
- Hydrant Maintenance - click anywhere on the GeoPlan or on the hydrant for which the maintenance is to be created.
- Valve Maintenance- click anywhere on the GeoPlan or on the valve for which the maintenance is to be created.
- Meter Maintenance - click anywhere on the GeoPlan or on the meter for which the maintenance is to be created.
- User Defined Repair - click on the GeoPlan location where the new object is to be added.
- The Create Scheduled Tasks dialog is displayed.
- Select the type of repair to be created and set the creation options as required.
- Click OK to create the task.
All surveys can be created by clicking anywhere on the GeoPlan. However, line based geometry tasks such as pipe repairs or pipe cleans will not have any geometry and will not be associated with any asset. This will have to be done manually in the repair property sheet.
Each repair type can also be created via the Scheduling | Create scheduled tasks option from the Network menu or the button of the Scheduling Tools Toolbar. Both alternatives also lead to the display of the Create Scheduled Tasks dialog.
Manhole Repair and Pipe Repair objects can be created automatically from a selection of manhole and pipe objects:
- Select manholes and pipes for which repairs are to be created on the GeoPlan Window
- Choose Selection operations | Create repairs for selected objects from the Selection menu
A manhole repair is created for each currently selected manhole and a pipe repair for each currently selected pipe.
The name of the repair is automatically generated based on the manhole / pipe ID. If a repair of the same ID already exists at a selected manhole or pipe, a suffix ".n" is added to the Repair name, where n is a number from 1 to 99. If a unique ID cannot be created, an error message will be displayed and the Repair object will not be created.
Resourcing objects (Resources, Materials, Approval Levels and Orders) are created in the Resource Grid. Please refer to the Creating Objects on the Network Grid Window section of this topic for further details.
To create a polygon or line using the New Object tool:
- Select a polygon or line to be created from the New Object Type dropdown list.
- Click with the left mouse button to add the first point of the polygon or line to the GeoPlan.
- Click on one or more intermediate points to add vertices. (To delete a previously drawn line, press the backspace key. Each previously digitised line can be deleted in turn in this way.)
- To finish marking out the object, double-click on the mouse button:
- For a polyline, the end point is added at the last point clicked on before the double click.
- For a polygon, double clicking closes the polygon.
If the new object is directly adjacent to an existing polygon or line, vertices of the new object can be snapped to vertices of the adjacent object. Individual points or a series of points can be snapped together.
To snap individual vertices in the new object to vertices in existing polygon and line objects:
- Ensure that snapping mode is switched on.
- Click the left mouse button to add each new vertex. To snap the new point to an existing vertex in another object, move the cursor close to the existing vertex.
- When the cursor is close enough to the existing vertex, a cross will be drawn over the vertex.
- Click the left mouse button and the new point will be snapped to the existing vertex.
Once the points are snapped together, they can be moved as a single point, as long as snapping mode is on.
To snap a series of vertices in the new object to a run of vertices in an existing polygon or line object:
- Ensure that snapping mode is switched on.
- Click the left mouse button to add each new vertex. To snap a series of new points to points in another object, start by snapping the first point of the series to the other object:
- Move the cursor close to the existing point. When the cursor is close enough to the existing point, a cross will be drawn over the point.
- Click the left mouse button and the new point will be snapped to the existing editing point.
- Move the cursor close to the final point of the series on the existing object. When the cursor is close enough to the existing point, a cross will be drawn over the point.
- There are now two options (these options will have the same effect when snapping to a polyline):
- Hold down the CTRL key and click with the left mouse button to follow the existing object by the shortest route.
- Hold down the ALT key and click with the left mouse button to follow the existing object by the longest route.
- A new point will be created to match each point passed in the existing object. The pairs of points will all be snapped together.
Once the points are snapped together, they can be moved as a single point as long as snapping mode is on.
Nodes can be created in the Long Section. Nodes created in this way will always be inserted into an existing link.
To create nodes on the Long Section Window using the New Object tool:
- Select Node as the type of object to be created from the New Object Type dropdown list on the GeoPlan Tools Toolbar.
- Click New Object () to turn on New Object mode.
- Click on the Long Section on the link into which the node is to be inserted. The Create New Node dialog is displayed.
- In this dialog:
- Enter a unique node name. (The Node ID will be automatically populated if Automatic Node Name Generation is switched on.)
- Select type of node to be created.
- If inserting a node into an existing pipe,check the Split box, select the pipe to be split and set a flag for new pipe lengths and invert levels if required. If working with a Collection Network, optionally check the Automatically Split CCTV Surveys box to split CCTV Surveys associated with the link to be split.
- If adding a node as a lateral connection, check the Add lateral node box and select the pipe to which the node is to be added. See Adding Lateral Inflows to Pipes / Links for further information.
- Click OK. The new node is inserted into the link and displayed on the GeoPlan.
- Select the correct Grid Window for the type of object to be added.
- Scroll the grid down to the append row. The append row is marked with a in the left hand column.
- Type information for the new object in the primary key columns of the append row. As soon as any data is entered the icon on the left will change to a . Other parameters can be added to the append row now, but it is not essential.
- To save the new object, move off the current row by clicking on another row in the grid. A unique name must be entered; if the object name is not unique, a message will be displayed. Click on OK on this message and either type in a unique ID or delete the duplicate ID from the cell, right-hand click on the row and select Delete Row.
It is possible to create InfoAsset Manager network objects via the Object Browser window. This window allows users to inspect object relationships.
Note that for new objects, geographical data fields may be defaulted to that of the parent object. Is it highly recommended to verify and edit this data on the Property Sheet that is subsequently displayed.
Refer to the Creating objects section of the Using the Object Browser Window topic for more details.
