Exploring Polarimetric Synthetic Aperture Radar (PolSAR) potentiality for landslide detection. Case study: Large-scale landslide in the Pan-American Highway Corridor in the Andes Mountain region in Colombia

, 2023
Background: Tropical mountain regions face adverse and worsening geohazards caused by climate related conditions, affecting large geographic areas worldwide. Landslides not only cause affectation to the people life, but they can affect the infrastructure challenging the ability of emergency authorities to assess the extent of the affected area.
