Azbest Detector
Screen selected roofs for likely asbestos-cement (eternit).
Drop a satellite screenshot or click to upload
A clear aerial/satellite image of the roofs you want to check. PNG or JPEG. Next you’ll draw a box around each roof to scan.
Help it detect better
After a scan, use the buttons under each roof to mark its real material.
- Every correction you submit saves that roof image together with the correct label.
- Those labelled examples build a dataset to train a dedicated model that learns local roof styles.
- The more roofs you verify, the better it gets at telling asbestos from look-alikes (grey metal, weathered concrete).
- Your local knowledge — roofs you can confirm in person — is the most valuable signal of all.
