Semi-automatic and manual shallow landslide inventories of two extreme rainfall events.

This dataset contains the polygons of automatic and manually based shallow landslides related to two extreme rainfall events. The dataset, in KML format, can be visualized on a GIS or the satellite image layer of Google Earth. With more details, it is possible to find: AOI_2016: The study area of the extreme rainfall of November 2016, Tanerello and Arroscia Valleys NW Italy. The 2016_PL: The inventory of potential shallow landslides semi-automatically mapped on the base of Sentinel-2 images related to extreme rainfall events that hit NW Italy in November 2016 The 2016_ML: The inventory of shallow landslides manually mapped on high-resolution images of Google Earth, related to extreme rainfall events that hit NW Italy in November 2016 AOI_2019_large: The study area of the extreme rainfall of October 2019 NW Italy. AOI_2019: The testing area of the extreme rainfall of October 2019, Gavi Area NW Italy. The 2019_PL_all: The inventory of potential shallow landslides semi-automatically mapped on the base of Sentinel-2 images related to extreme rainfall events that hit NW Italy in October 2019 (whole Study area) The 2019_PL: The inventory of potential shallow landslides semi-automatically mapped on the base of Sentinel-2 images related to extreme rainfall events that hit NW Italy in October 2019 (Gavi test area) The 2019_ML: The inventory of shallow landslides manually mapped on high-resolution images of Google Earth, related to extreme rainfall events that hit NW Italy in October 2019 GEE_Script: List of codes used in Google Earth Engine to produce NDVI time series or averaged NDVI on some sample studied areas With more details, the Google Earth Engine scripts used are: NDVI Time series of some sampled areas to select the best pair of images for the PL creation (Tanarello and Arroscia Valleys and GAVI AOIs https://code.earthengine.google.com/8f4d08db4d34099bb1a4cd1fd15bf05b?noload=true Sampled NDVI Time series from different intersection cases for Tanarello and Arroscia Valleys study area https://code.earthengine.google.com/47e5883e0fe7beae589df4c42421dd3b?noload=true Sampled NDVI Time series from some test areas over the Gavi study area https://code.earthengine.google.com/e97fd46102cca3ee25b441a8ebff8400?noload=true Multi-temporal averaged pre- and post-event NDVI (NDVI_var ) for the whole Gavi study area https://code.earthengine.google.com/f982f831c74afcca3d1a95a9dd18424b?noload=true Multi-temporal averaged pre- and post-event NDVI (NDVI_var ) for the whole Arroscia-Tanarello study area https://code.earthengine.google.com/a3390b262cef1b5f42837c88d8791b5b?noload=true
