This is a polygon shapefile inventory of 183 coseismic and climate-triggered landslides in the south-western portion of Langtang Valley Nepal. All mapped landslides were those visible in the landscape during the period 2017 – 2018. Landslides were mapped using a combination of field and remote sensing methodologies (see lineage). The inventory includes the landslide locations, perimeters (Length field), areas, types, and whether a given landslide was mapped in the field or remotely. These landslides were mapped for a range of purposes, from conducting landslide susceptibility assessments, to investigating landslide processes and preconditioning.
