This study introduces a two-stage method for monitoring impervious surfaces (IS) with high accuracy and resolution. We apply U-Net CNN to mask stable areas and Continuous Change Detection (CCD) for IS change analysis over time. Achievements include excellent IS detection (OA=0.96), change identification (OA=0.94), and timing (OA=0.77). The approach emphasizes computational savings by targeting significant changes and demonstrates CCD’s efficacy using PlanetScope imagery for accurate IS tracking.
