An Event Landslide Inventory Map (ELIM) shows the location and extent of landslides caused by a specific natural trigger, such as an intense rainfall event, a period of prolonged rainfall, a rapid snowmelt event, or an earthquake. LAMPRE has advanced methods and tools to prepare ELIMs exploiting high and very-high resolution optical satellite images.
The methods and tools developed by LAMPRE allow preparation of an ELIM anywhere recent landslides have left discernible signs captured in the optical satellite images. The methods and tools work best in vegetated terrain where the event landslides have removed the vegetation, and are applicable in areas ranging from a few to a few hundred square kilometres.
LAMPRE can prepare an ELIM within hours to days after a landslide triggering event, provided adequate satellite imagery is taken shortly after the event.
Civil Protection authorities use ELIMs in the aftermath of an event for improved rescue and recovery operation.
Planning & development authorities use ELIMs to identify areas recently affected by landslides, and avoid dangerous areas.
Transportation authorities & utility managers use ELIMs to evaluate the impact of landslides on transportation or utility network.
Agricultural & forest agencies use ELIMs to assess the impact of landslides on crops and forests.
Scientists use ELIMs to prepare multi-temporal inventories useful for erosional studies, and to determine the statistics of landslide areas.
LAMPRE prepares ELIMs at scales ranging from 1:25,000 (smaller scale) to 1:5000 (larger scale) in periods ranging from hours to days after the delivery of the high resolution (HR) and very-high resolution (VHR) optical satellite images. LAMPRE uses pre- and/or post-event satellite images, and delivers ELIMs in raster and vector formats.
