ALDIv1.1.0

The Automated Landslide Detection Index (ALDI) uses pixel-wise NDVI differencing of Landsat time series within Google Earth Engine accounting for seasonality. Its aim is to recover the locations of landslides triggered by a known event (e.g. earthquake) using freely available archival imagery. Testing for a set of recent large earthquakes suggests that ALDI can identify landslide affected pixels as skillfully as published manually mapped inventories in the majority of cases. This version of ALDI implements the method and uses the parameters described by: Milledge, D.G., Bellugi, D.G., Watt, J. and Densmore, A.L., 2022.
