AI-Powered Satellite Imagery Analytics & Change Detection
Analytics
Satellite imagery analytics
Run change detection, vegetation, and water analytics in Pera Portal.
Change Detection
Automated change detection, powered by AI
Upload imagery from two dates over the same area. The models compare them and return the areas that changed, segmented into objects. No training data or labeling required.
Current models
Change detection runs on deep learning segmentation models, applied to two acquisitions over the same area.
No training needed
The pre-trained models work out of the box. No data labeling or model training: upload imagery and changes are flagged automatically.
Built on Segment Anything
Meta's Segment Anything Model (SAM) segments each detected change into discrete objects, so individual features can be tracked across dates.
