Auto Add Linear/Area Nodes
Overview
Auto-add nodes lets a surveyor walk a route and have Soarvo Mobile automatically drop nodes onto a linear or area feature whenever they move more than a configurable distance. Faster and more consistent than tapping the map for every vertex.

How to Enable Auto-Add Nodes
In the web portal, edit the linear or area feature type you want to enable auto-add for:
- Add a numerical attribute named
_AUTO_ADD_NODES. - Set its default value to
!MODIFIER-HIDE;1.23— where1.23is the minimum distance in metres before a new node is added.
The !MODIFIER-HIDE prefix hides this attribute from the user-facing form; the semicolon separates the modifier from the actual default value.
Using It in the Field
- Start a new linear or area feature.
- If the feature has no existing nodes, your current position is added as the first node.
- Tap the Start button to begin auto-adding nodes as you walk.
- Each time your distance from the last node exceeds the configured threshold, a new node is added.
- Tap Stop to pause auto-adding. You can resume with Start again, or save the feature.
💡
Tip: Pick the threshold based on your survey precision needs. 0.5–1.0m is typical for utility tracing; 3–5m for general boundary walking.
