Landonline contains numerous examples where two or more marks exist very close together. Often these are not visible to the naked eye even at a scale of 1:1.
In many instances these are legitimate marks:
- they may represent adopted, disturbed or unproven marks that are in close proximity to each other; or
- there may be a very short vector between adjoining marks.
In other instances there may be marks in Landonline that are incorrect:
- one or more nodes may not be linked to topology but are very close to a node that is. Some of these nodes are not legitimate, and
- some nodes may be duplicates (not linked to new surveys, thus creating duplicate marks).
- If the nodes are duplicate (mark names are the same, not disturbed or replaced), please advise LINZ by adding a note to the survey report.
It is important that you select the correct mark required for either linking or searching purposes.
To select the correct mark in these circumstances:
- Select the Object Information Tool icon and click as close to these nodes as possible.
- Select the drop down arrow next to the 'Feature Id' field.
- There will be two feature ids listed. Select one of the ids in the drop down box.
- The spatial screen will briefly highlight that node.
- If it is not the node you wish to link to, select the other feature id.
- Take a note of the node id to which you wish to link.
- Open Mark Details screen.
- Select Link Mark.
- Enter the node id you noted down into the Node Id field.
- Select ‘Search Now’.
- Select ‘Select’.
Your mark is now linked to the correct Landonline node.
