Polygon inventory of 183 landslides mapped across Langtang Valley, Nepal (NERC Grant NE/L002582/1)

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.

Statement: Landslides were mapped using a combination of field mapping and remote sensing. Field mapped landslides were identified during walk-over surveys conducted in October 2018. The locations and geometries of these landslides were recorded using a hand-held Garmin GPS unit and a TruPulse laser range finder. The exact geometries of these field-observed landslides were then corroborated using WorldView/GeoEye Satellite imagery from 2017. Furthermore, as not all landslides were accessible in the field, additional landslides in the landscape were mapped from the WorldView/GeoEye imagery alone, where all visible landslides in the imagery were delineated as polygons that included the source, runout and deposition zones of each landslide. The general type of each landslide was also classified according to the terminology of Varnes (1958).
