Landslide Monitoring Of Natural Terrain Area In Central Aceh Using Interferometric Synthetic Aperture Radar Techniques

Surface deformation measurements are critical for landslide studies. Interferometric Synthetic Aperture Radar (InSAR) technique is very important for landslide studies as it contributes to soil surface deformation monitoring methods for slow movement rates before landslides occur. The technique has...
