In our examples we have shown the process and referred to capturing a balance road. The process is the same for hydro or rail balance parcels.
The balance parcel process is used during survey capture to deal with the balance of a parcel that does not need to be dimensioned but must be created to keep the database topology correct. In this case the vectors don't need to be captured.
For example: A road legalisation stops part of a road. At survey capture, the whole road parcel is extinguished in the survey. New sections will be created for the part of the road to be stopped. The remainder of the existing road parcel must be dealt with as a balance parcel with a parcel intent of ‘Road’ to keep the cadastral database up to date.
To capture a balance road parcel, you will need to:
- Extinguish the underlying road parcel.
Adopt the remaining lines of the balance parcel into your survey, by:
- adopting individual lines using the Inspect and adopt tool
- adopting multiple lines using the Draw to select tool
- adopting multiple lines using the Process balance parcel boundary functionality.
For more information on which method to use, see:
Pros and cons of each method- Create and link the balance road parcel.
1. Extinguish the underlying road parcel(s)
Open the Existing Parcels panel and select Add/remove existing parcels.
Left-click on the underlying parcel in the spatial view to select it. This should be the existing road parcel that you are creating a balance parcel over. Select Add/remove selected parcels to add the parcel to the Existing parcels panel.
The parcel will appear at the bottom of the list, with its action set to Extinguished.
2. Adopt the remaining lines of the balance parcel into your survey
You can choose between 3 methods to adopt the remaining lines for your balance parcel:
- Adopt individual lines using the inspect and adopt tool.
- Adopt multiple lines using the draw to select tool.
- Adopt multiple lines using the process balance parcel boundary functionality.
Before you start adopting lines for your balance parcel
Before creating your balance parcel, check for unlinked marks representing a node at the end of a line you are adopting.
You will need to link these mark(s) before adopting the line, or a second mark will be adopted in the same position as your captured mark.
In the example pictured below, mark 1004 and mark 1012 are at the ends of lines that will be adopted to create the balance parcel:
- Mark 1004 is linked so no action is required.
- Mark 1012 has an underlying node, but is unlinked. You would need to link this mark before starting the balance parcel process.
If your unlinked mark has no underlying node and is the end position of your balance parcel, you will need to either:
- add a vector from your mark to the next existing Landonline node
- raise an exception request to have a node added at your mark’s position.
In this example, mark 23 is positioned part way along an underlying vector and has no underlying node (orange underlying mark). You should add a vector from mark 23 to the underlying node at a, then start the balance parcel from the newly linked mark at position a.
Method 1: Adopt individual lines using the Inspect and adopt tool
Select the Inspect and adopt tool from the Tools control toolbar.
Left-click on a line around the parcel to select it. The line changes to pink when selected, and an Underlying line pop-up box appears.
- The icons at the bottom right of the pop-up box allow you to:
capture a single line
capture multiple lines
Select Capture this line to add the line. You will see a success message at the top right of the screen when the line has been captured.
The captured line will appear black, and the mark at the end of the line is now linked.
Continue around the parcel to capture the remaining lines.
Alternatively, select Capture multiple lines to add more than one line at a time. The selected line changes to a dashed pink line, and the Capture multiple underlying lines panel opens.
Left-click on the lines you want to select. The selected lines appear in the panel.
Select Capture selected lines to add these lines.
The lines are captured, their marks linked, and a success message displays at the top right of the screen.
You can view adopted or captured lines in the Lines panel, under the Right-lines tab.
Check the Layers for each line and edit them if required. In this example, all our lines should be Primary, so the Pri, Sec lines will need to be changed.
Method 2: Adopt multiple lines using the Draw to select tool
Select Draw to select features from the Tools control toolbar.
The Draw to select features panel opens. Select:
- Spatial data: Underlying
- Layers: Lines
Use your mouse to draw around the lines you want to adopt.
All selected lines will turn pink, and be added to the panel. You can deselect any unwanted lines by holding CTRL on your keyboard and left-clicking on the line(s).
Select Adopt to adopt the selected lines.
The lines are adopted, their marks linked, and a success message displays at the top right of the screen.
You can view adopted or captured lines in the Lines panel, under the Right-lines tab.
Check the Layers for each line and edit them if required. In this example, all our lines should be Primary, so the Pri, Sec lines will need to be changed.
Method 3: Adopt multiple lines using the Process balance parcel boundary functionality
Process balance parcel boundary automatically adopts all remaining lines in your balance parcel.
Select the Inspect and adopt tool from the Tools control toolbar.
Select the underlying parcel. The parcel changes to pink when selected, and an Underlying parcel pop-up box appears.
- The icons at the bottom right of the pop-up box allow you to:
process a balance parcel boundary
adopt boundary vectors
Select Process balance parcel boundary. The Process balance parcel boundaries panel opens.
Select the start node for the remaining parcel boundary you want to capture. The node turns pink as you select it.
Select the end node at the other end of the parcel boundary.
Landonline automatically chooses which path to take around the underlying parcel. A pink dashed line appears around the parcel boundary that will be captured.
Select Highlight alternative sequence to change the line to the other path if necessary.
Select Capture balance parcel at the bottom of the panel.
The lines are captured, their marks linked, and a success message displays at the top right of the screen.
The marks will be in the Marks panel. You can view the captured lines in the Lines panel, under the Right-lines tab.
You may also see lines in the Irregular lines tab, depending on how they were originally captured in Landonline.
3. Create and link the balance road parcel
To complete your balance parcel:
- Check the captured or adopted lines for your balance parcel are in the correct layer.
- Then, create a new parcel in the New parcels panel and link it.
Check lines are in the correct layer
- Open the Lines panel and select all Irregular and Right lines. They will highlight in the spatial screen.
Check the Layers for each line around your balance parcel and edit them as needed. In this example, all our lines should be Primary, so the Pri, Sec lines will need to be changed.
Create and link the new parcel
Select New parcels in the Workflow control bar to open the New parcels panel.
Select + Add new parcel.
Double-click the Intent field for the new parcel. Select Road from the dropdown list.
Parcel Intent for Railway or Hydro balance parcels:
Select Railway or Hydro for these types of balance parcels.
Open the Appellation panel by double-clicking in the Appellation field for the new parcel.
Untick Appellation required for this parcel. The remaining fields will change to grey. Select Save appellation.
The parcel is given a CSC parcel number. This will match the ID number.
The Layer is automatically set to Primary for parcel intent Road or Railway.
Note for Hydro parcels:
Double-click the Layer field and select Primary for a Hydro balance parcel.
Left-click the 3 dots at the end of the row. Select Link to link the parcel.
Left-click to select the parcel in Spatial view. The selected parcel will turn pink. Select Link Parcel.
The balance road parcel is now linked in the New parcels panel.
The parcel also shows as linked in the spatial view. Its CSC number appears spatially.
Pros and cons of each method
There are pros and cons for the 3 methods of adopting balance parcel lines into your survey. Each scenario may differ, so learn to use the most appropriate tool for your situation.
Method 1: Adopt individual lines using the inspect and adopt tool – this method is the quickest way to add a small number of lines, however it is relatively easy to accidentally miss a small line in the process.
Method 2: Adopt multiple lines using the draw to select tool – this method is the quickest way of adopting many lines from multiple parcels. A common scenario where this is helpful is where there is a large parcel including easements that are allowed to be accepted – so long as the rules allow it. The risk is that it is relatively easy to accidentally miss a small line or add extra unwanted lines in the process.
Method 3: Adopt multiple lines using the process balance parcel boundary functionality - this method is the fastest way to capture the balance of a single large parcel. It is also setup in a way that makes it very difficult to miss any lines as you select the start and end points. However, the tool is a little bit cumbersome due to the extra steps involved if you need to capture a lot of parcels, or only a small amount of information.
