An Integrated PS-InSAR and K-Means Clustering Framework for Roadbed Deformation Susceptibility Assessment Supporting Sustainable Urban Road Management in Daegu, South Korea
Long-term deformation of urban road networks can compromise infrastructure performance and requires spatially continuous methods for identifying segments that warrant targeted monitoring. This study integrates Persistent Scatterer Interferometric Synthetic Aperture Radar (PS-InSAR), geotechnical data, multivariate k-me...
