Abstract

The findings of the statistical models based on geographic information systems (GIS) for creating landslip susceptibility maps utilising remote sensing data and geographic information systems for the Rishikesh to Yamunotri corridor of Uttarakhand are presented in this study. Cartosat, Landsat, IMD, and India water resources data were used to extract ten factors: slope, aspect, soil, lithology, NDVI, LULC, distance to stream, precipitation, distance to road, and elevation. Using GIS-based statistical models, such as the analytical hierarchy process (AHP), which assigns ranks and weights to various factors to determine which factors are more responsible for landslides, the relationships between the detected landslide locations and these ten related factors were identified. The three landslide zone categories, high, medium, and low, on the landslip inventory map were developed using various things like field surveys and digital aerial photos. Regional planning and hazard mitigation would benefit from these landslip susceptibility maps.
