AI field boundary (AI Boundary)
AI Boundary removes the most tedious step of field work: instead of tracing the field by hand, you simply click the field on the orthomosaic a few times and the built-in segmentation model draws the field boundary for you.
The model runs entirely on your machine — no internet connection is needed and your imagery never leaves the computer.
How to use it
Section titled “How to use it”- Open the Add menu and choose AI Boundary. The toolbar shows Click at least 3 points inside the field (⌥-click = exclude).
- Click at least 3 points inside the field on the orthomosaic — these are the include points. ⌥ (Option)-click marks an exclude point (e.g. an adjoining green strip or tree line). Undo removes the last point.
- Press Generate. The boundary is created, saved and opens immediately in vertex editing.
On heterogeneous, patchy fields spread the include points out — one on each bright or discoloured patch — so the model covers the whole field.
Refining the result
Section titled “Refining the result”After Generate the polygon behaves like any hand-drawn boundary in edit mode — include / exclude points are only available before generating:
- Drag vertices into place.
- ⌥ (Option)-click a vertex to delete it.
- Save keeps the changes, Cancel discards them.
If the result is far off, delete it and run AI Boundary again with more, better-placed points.
What the model does for you
Section titled “What the model does for you”- Runs locally — works offline; nothing is uploaded.
- Thins the vertices automatically (roughly one per 3.5–5 m). Spray drones process the polygon on board, so fewer points mean faster, more reliable uploads.
- Cuts obvious artefacts — spikes and false protrusions are removed automatically; borderline cases are left to you (exclude points, vertex editing).
Where else you’ll meet it
Section titled “Where else you’ll meet it”- AI vegetation analysis requires a boundary — if the project has none, the app offers to create one with AI Boundary.
- XAG route export — when you save an XAG route without a boundary, DroneField generates one automatically (the XAG cloud, nf.xa.com, requires it). See Field boundaries → XAG drones.
