AI Segmentation by TerraLab
AI segmentation for QGIS: detect and extract building footprints, trees, vegetation or any object from your raster, then refine & export as vector polygons
Draw a zone on your imagery, type what you want ("buildings", "trees", "solar panels") and get every match back as vector polygons. Or click one object and get its outline. It replaces tracing by hand.
• Automatic: every building, tree or other object inside the zone you draw, in one run, with a live preview. It runs on TerraLab servers, so no graphics card is needed
• Semi-Auto: click an object, add positive and negative points, get a clean outline. Pick "My computer" and it runs locally and offline, or "Cloud AI" and nothing needs downloading
• Works on the imagery you already have: orthophotos, drone and satellite images as GeoTIFF, JPG or PNG, and online basemaps (WMS, XYZ tiles)
• Review before you keep: right angles for buildings, expand, contract, simplify, round corners, fill holes, then export to GeoPackage, Shapefile or GeoJSON
• Installs itself: the model and its dependencies set up on first run, with no Python setup
• Free tier with no card. Plans and limits: https://terra-lab.ai/pricing
• Privacy: Semi-Auto on "My computer" sends nothing. "Cloud AI" sends a small image crop around each click to our servers. Automatic sends the imagery inside the zone you draw to our detection service
• Windows, macOS and Linux, QGIS 3.22 to QGIS 4
• 12 languages: English, French, Portuguese, Spanish, German, Italian, Dutch, Polish, Indonesian, Japanese, Chinese (simplified and traditional)
