AI Segmentation
AI Segmentation turns imagery into vector polygons in QGIS. Click one object to get its outline, or name what you want, such as "buildings", "solar panels" or "trees", and get every match across an area.
Two modes
| Mode | How | Where it runs | Counter |
|---|---|---|---|
| Semi-Auto | Click an object, get its outline | On your computer | None, free |
| Automatic | Name an object, get every match in a drawn zone | On TerraLab servers, no GPU needed | km² and object detections |
Use it
- Pick the imagery layer and draw the zone on the map. The panel shows its size in km² before anything runs.
- Type a word like building, tree or car, or pick one from the Library. Draw an example on the map when the object is unusual.
- Keep what you need with the confidence and size filters, correct the rest, then export one vector layer with its attribute table.
Free allowance and Pro
Every month: 1.5 km² of Automatic detection and 20 object detections, no card. Semi-Auto has no counter. Pro covers larger areas with a 7-day free trial; prices are on the pricing page.
